I'm not terribly fond of SqlTableEditor, partially because of the woeful lack of documentation 😅 but I suspect there might be a little bug or something. As a (untested) workaround, have you tried clearing the list of edited rows?
Dim saveDataTaskInfo As XFSqlTableEditorSaveDataTaskInfo = args.SqlTableEditorSaveDataTaskInfo
saveDataTaskInfo.EditedDataRows.Clear()
JackLacava, yes, I've tried calling clear() as you've shown with (I think) no effect. Could be the unit test where I tried it had slightly different conditions, it was a couple of days ago. I can try again.
