PowerGEOPAK SS4 Scanning Models upon exiting file

Hello, I am using PowerGEOPAK SS4 and my dgn file has about 15 models so it takes forever to close a file (at least 5-10 minutes) because of the Status "Scanning Model: x" dialogue box that goes through every single model.

Does anyone have the same issue/ any workarounds?

Thanks!
