Graphing interface graphs no refresh

I have a h AP ac^3 and hEX S. I recently updated both to RouterOS 7.19.3 and 7.19.3 Routerboard firmware.

My interface graphs are no longer refreshing in Winbox 3.42 no matter what I have the refresh time set to. Same for the the 4 beta and the web interface.

Is anyone else experiencing this issue? Any ideas at all would be appreciated.

Thanks.
