I have a RB2011 UIAS router, (v7.9) and Winbox 3.38, and I see there is a small bug in interface lists.
On my working place, we have several RB4011 and RB1100AH devices, and it happens too on that boxes.
If we go to Interfaces, and Ethernet, we can add/change columns to show more information.
First bug is that if we want to add Full Duplex Information, we see there are two options, but one of them gives empty values.
We have to use the other "Full Duplex" option, to display desired values.
But when we closing Interface window, changes are never saved and when opening again, and we have lost the "full Duplex" working column, and it appears the other option, the one which has empty values.
Is it really a bug , or am I doing something wrong ?
