[Help] Property Set Definitions duplicating for no reason

[aira_silva]

Hello!

I'm working on a document that needs parameters applied to "Pipes", "Structures", "Thin Surfaces", etc. I created a Property Set Definition (PSD) with all the necessary parameters.

For some unknown reason, the PSDs duplicated excessively, resulting in over 6,000 duplicated PSDs in our drawings.

I found an Autodesk Support Issue (https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/How-to-delete-dupl...) with a LISP routine that helped us merge the PSDs, but it was a time-consuming process.

After cleaning up the PSDs, I saved the document, made a backup, and continued working. I deleted some broken Surface references and then purged the drawing.

Suddenly, new PSDs appeared, as shown in the picture below.

Duplicated PSDs

The PSDs "SNR_IE (2)", "SNR_IE (3)", "SNR_IE (4)", and "SNR_IE (5)" are duplicates of the original "SNR_IE".

I didn't use any commands to duplicate the original PSD. My question is, what could be causing the PSD to duplicate?
