URE Pro edit restrictions add-on does not support TablePress due to its way of working with custom post type (more information here).

In order role can use “Add Media” button it should have ‘upload_files’ capability.

Send direct link to EasyAzon plugin if its available at wordpress.org/plugins
I need access to it in order to test and check what permissions it requires.

Role is not available for deletion in URE while it was granted at least to one user. Revoke role from all users. You will see it after that at the list of roles for deletion at URE.
