Uncoupling nodes

I recently discovered a problem that really annoys me. I can couple nodes by holding ctrl and middle click but I can't uncouple them using THE SAME COMBINATION. Earlier it worked perfectly but now the game just doesn't seem to want me create roleplay scenarios (towing...)
I even tried it in safe mode but it still didn't work for me. I am really annoyed by this problem so could anyone maybe help me in any way?

 

There is no decouple tip,
It works some times most of the time is refuses to unclip, even when clicking on the coupled node

 

I have no way of recording a video on my pc,
I can make a replay through the replay system and share the replay file if that works

 

Ill try in about 10ish mins, im away from my pc

Dont have a phone, i have an ipad but the camera is extremely bad ( my phone kicked the bucket a couple of weeks ago)
I can explain the issue if that helps

 

Ive just found out there is a preinstalled screen recorder on my pc, i cant do it now but when i can ill check it works and send through a vid

 

Decoupling nodes works fine for me. Just gotta make sure you're on the right node, and the "Decouple node" message appears

 

Can you disconnect nodes that you connect together and not in the air?
Lets say you spawn in 2 boxes and connect them by one node to eachother, can you undo it?

That doesnt work either

 

I tried that offcamera too, ill record another vid soon

Huh, it does actually work when clicking on it with left click, but why do you need to click on the node to decouple it? Id prefer clicking on the node without left click
