Deleting "Comment" in Ontology editor

[HTsybenko]

1. Open "Ontology Editor"

2. In the opened window (Structure 0), click on deleting the “comment” property.

   A message occurs:
   /home/htsybenko/Temp/envir/lib/python3.10/site-packages/pasta_eln/guiStyle.py:131: RuntimeWarning: Invalid return value in function QAbstractTableModel.flags, expected PySide6.QtCore.Qt.ItemFlags, got NoneType.
   self.triggered.connect(lambda : widget.execute(command))

3. If saved after that, another warning appears:
   /home/htsybenko/Temp/envir/lib/python3.10/site-packages/pasta_eln/GUI/ontology_configuration/ontology_configuration_extended.py:434: RuntimeWarning: Invalid return value in function QAbstractTableModel.flags, expected PySide6.QtCore.Qt.ItemFlags, got NoneType.

@HTsybenko I have observed this also multiple times, but the functionality as such will not be affected by the error, deletion would succeed right or do you see any actual issue also associated with this error message?
