A few Bugs related to the new skin

Symptom

The new version of the skin still has many unfinished areas. I have compiled the issues I encountered as follows.The JSON file content is as follows. For ease of viewing, only the key content is retained:

1.The following settings have not taken effect:

{
    "General Menu": {
        "Undo": 0,
        "Redo": 0
    },
    "System": {
        "Scripts": {
            "Scripts": {
                "&": {
                    "copy": 0
                }
            }
        }
    },
    "Files": {
        "File": {
            "&": {
                "copy": 0
            }
        },
        "Text File": {
            "&": {
                "copy": 0
            }
        },
        "Directory": {
            "&": {
                "copy": 0
            }
        },
        "Script": {
            "&": {
                "copy": 0
            }
        },
        "Support Info": {
            "&": {
                "copy": 0
            }
        }
    },
    "PPP": {
        "PPTP Client": {
            "&": {
                "copy": 0
            }
        },
        "SSTP Client": {
            "&": {
                "copy": 0
            }
        },
        "L2TP Client": {
            "&": {
                "copy": 0
            }
        },
        "PPPoE Client": {
            "&": {
                "copy": 0
            }
        }
    }
}

2.The following settings work in the regular interface, but once the webpage width is reduced and the responsive design alters the layout and appearance of the left navigation bar, these elements appear below the navigation menu. After confirmation, they are all functional:

{
    "Terminal": 0,
    "Advanced": 0,
    "Quick Set": 0,
}

3.The following translations have not taken effect:

{
    "PPP": {
        "PPPoE Scan": {
            "Output": {
                "Service": {
                    "name": "ServiceName"
                },
                "MAC Address": {
                    "name": "MAC"
                },
                "AC Name": {
                    "name": "AC"
                },
                "tab": "OutputInfo"
            }
        }
    }
}

All of the above were edited through the skin designer. After I manually changed it to this:

{
    "PPP": {
        "PPPoE Scan": {
			"Service": {
				"name": "ServiceName"
			},
			"MAC Address": {
				"name": "MAC"
			},
			"AC Name": {
				"name": "AC"
			},
            "Output": {
                "tab": "OutputInfo"
            }
        }
    }
}

The translation for "Service","MAC Address" and "AC Name" has taken effect, but "Output" still does not work.

4.I cannot find any place where the names of the "Upload..." and "Download" buttons in the "Files" section are translated.

The RouterOS system version is the lastest v7.21beta3, and the issue has been tested on multiple devices with different architectures. The problem occurred the same way on all, so it should not be related to the hardware.

I have submitted a support ticket:SUP-202680.

Considering that fixing the bugs in the skin designer will take some time and I need to deliver to the client urgently, it would be best if anyone could provide a way to handle this by directly editing the JSON file content.I would be very grateful!

Thank you very much!
