Hi, kpower, and welcome to Bob! 
– did you try a search on BoB?
It’s been a while since I tried the Master /shared setup.
But, it sounds like your ShData is set up to use what is on the server. You should be able to change it so that it uses the ShData / LocData on each user’s hard drive.
Here’s one topic where it is discussed. and here’s another post within a topic that might help you.
