In AC13 the pen swing is part of the Model View Settings not of the individual doors.
Recommendation is to do a search for the "bug" in the forums, if nothing found then post the question. Somebody will forward the information if it is a bug.
The Official procedure is to email your reseller with the information so that he can forward it to GS.
