Error when copy-pasting a field in JS Designer

[paroxit]

Hello, one of our user is trying to copy a field to another place. He was able to do that for a while, but after some point copy-paste throws this error ;

"Please use filters collection"

We've searched over the internet and couldn't find anything. Can you help ?
