get all files - not working for a few users

We are using eB  version 15.5.1

We know about removing the last "/" from the path.

For most people, so long as they remove the "/" get all files works ok, but there are at least 2 users who this does not work for. They can do other file handling tasks, just not get all files.

Is there anything specific to those users that we should check to resolve this issue?

Thanks
