Missing data fields in W3 Object Editor

Level 3
Apr 7, 2020
Hello fellow Hive members!

A few days ago, some data fields started to go missing in the Objet Editor. I've specifically noticed the ability tabs for Units, as they're super useful, but there may be others :/ I tried using Ctrl + F to see if they had moved or something, but they were nowhere to be found. The weird thing is that they show up in the Campaign's Unit Editor.

I haven't updated my W3 version (I have a pretty old version, not Reforged) since and I can't find a solution on the web. Does anyone know what could have caused that problem? I added screenshots (it's in French, but you get the idea) to show you.

Thanks a lot for your help :)
