Units lumped in with my com when i press hotkey 1

I have this problem that when i put my com in group 1 (when pressing ctrl+1 and recently put it to always be 1 in hotkeys)

it sometimes (not always) lumps in some other units or factory


It can really mess up a game (especailly 1v1 when time is important)

not sure why but it seems redbacks get lumped in more than others, but might be coincidence , now i dont remebmer cause did not happen recently but i think it adds constructors too sometimes also



Would love if someone can help solve this issue i have (i think it exists for years) so that i can have a com in group 1 (button 1) and not get random units (or factory) lumped in during the game

Thanks for reply

I think i might have this issue for years

I have this issue long before i choose a pre choosen group (And at the moment its basically "q" button for factory ... and 1 for com ...) so i dont think anything like that causes it

Meaning i dont think anything in hotkeys setting i did caused this - cause i had this issue long before i even tried to change anything there
