My only mod is Kerbal Engineer Redux. Here's a screenshot : https://imgur.com/a/6S0VXmX EDIT: Ok it works now, the message is still showing but I can select my decouplers again. I restarded the game a few times and it seems to have resolved it.

I was building a ship in the VAB when I saw that every single decoupler isn't selectable, and when I put my mouse on it it says "Crossfeed toggles in Editor and Flight. Default off." which I'm sure isn't usually written. Any idea to resolve the issue ? Thanks for the help. EDIT : I restarted my game a few times and I can select and place my decouplers again, though the weird message is still showing. Seems to be resolved for now.
