Hi everyone
I'm trying to tidy up what some of our users are able to search on in the Advanced Find and Advanced Filter screens with CRM. I've successfully hidden fields by changing the Searchable option to No, but I'm having problems hiding a full Entity, or what I think are Entities.
I've read in a few places that restricting the Read permission of an Entity in the Security settings screen (for the Security Role that the user is assigned) will solve this, but it doesn't work for me.
The users in question are part of the Security Group shown below:

The Entities that the users do not have Read access to are hidden from the Advanced Find and Advanced Filter screens, but many more still exist as shown in the image below. I'm unable to find these in the Security screen.

Does anyone know how I can restrict access to these as well?
Many thanks,
Jon
