Slot Error!!

i ALSO ALREADY HAVE THE MOST UPDATED VERSION OF S4S.
I created an end table, and to add more slots faster I imported it into TSRW to add deco slots. I then exported it to a .package and re-opened it in Sims4Studio and I got this error under slots:

"System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.IO.EndOfStreamException: Attempted to read past the end of the stream.

I hope an update for adding slots easier in the future then just adjusting the coordinates (which when you are like me and looooove slot spaces, its a hassle).
Thank you in advance!
