New site members not being auto added as friends

Hi,
I have a BuddyPress community setup and also using Restrict Content Pro and WooCommerce on the site.
Rather than using the BP registration system we are using Gravity Forms with its user registration addon.
New site members are being auto added to groups and given BP member types and a RCP member level so all that is working.
My WP user profile has the checkbox checked to say add all new members as friends for me – I am a site administrator if that makes any difference.
I do have one other member setup to get all new friendships added and they are just a standard WP BP user and they aren’t getting friends added either.

All site users have custom WP user roles that we created using the user roles editor Pro plugin if that matters.

Using latest versions of WP and plugins.

It would also be great if there was a feature to retrospectively make me into friends with all site users.

What other info do you need to help diagnose the problem?

Thanks,
Dale.
