Qt for Python (PySide/Shiboken)

I'm sorry for the late reply, I had put this project aside due to work related stuff. I created a minimal working example here: https://pastebin.com/0H3agZf4 (I hope that for simple examples pastebin is good enough, I can create a repo if necessary instead) The problem can be observed when creating new records with the "+" button and then trying to remove those with the "-" Also strange behaviors occur when editing the new points and then trying to delete any of those. I would really appreciate some guidance on this issue, I'm more then open to share more info is needed P.S. I'm using Python 3.10.2
