So I think I have found a bug in the GUI that is messing with my configuration. I duplicated the folder to create one of my kid’s HP layouts. I removed several tabs and it seems to have messed up one of the rooms as a result. All the items on the last tab were removed. When I opened the Options, the matrix of tabs/devices looks like this:
Looks like there is a mismatch between the tabs and number of columns allowed for the devices for those tabs. Any ideas?
