This is a known issue with AhsayCBS / AhsayOBM version pre-7.17.0.30.

For files and folders on Google Drive with name containing any underscore ( _ ) (also called underline) character, for example:

name_with_underscore

The underscore ( _ ) characters are returned as slash ( / ) characters (which are incorrectly interpret as path separator):

name/with/underscore
