I don't use BiDM but indexing sounds like the key ingredient. Has it had time to rebuild the index?
There are times where Windows updates remove the Solid Edge properties from the Indexer. You also need to make sure your folder you are using are set to be indexed.
To add the SE props back,
Run CMD in administrator and after run :
regsvr32 "C:\Program Files\Solid Edge ST10\Program\sepropertyhandler.dll”
