I can add laebls normally, but I can not copy labels by properties copy in Edit selected Objects
And I tested other object like queue, it can work normally. I can copy label as I excepted
Edit Selected Objects exception
The same exception also occurred in Control Area. I also tried to copy a label on conveyor, the exception was appeared again.
I checked the nodes where the error message was prompted, and I replaced the node from old version.
It worked, but it will return to default state everytime
