When we were still using Fabrication we used two different databases for material, Autodesk OTB and Building Data. I hated switching back and forth between databases. So every year after we updated the software I always just submitted a help ticket through our Fabrication vender/reseller and he'd do a remote login and merge the two databases for me so I didn't have to switch back and forth between the two and they were all-in-one. It made life so much easier. They might be able to do the same for you and your databases, and it might fix the issue.
