Need help. issue when adding a module

[CobraGuru]

Hello,
I'm at the simulator to build a new station
I'm trying to add a module but game put it in red, rejecting it's position, while nothing around is blocking. Happens often and dunno what to do

I've observed the same issue in game. Editor suggests to place the module on the position and highlights it in green, but when I put module it rejects it and shows in red. When exit the editor and enters it again, take new module and this usually solves the problem.
