Custom user role not showing in dropdown for Settings > Admin

I’m facing an interesting issue.

A custom user role I just created is not showing in the dropdown at Settings > Admin.

I created the custom role just for choosing it in “Record Edit Access Level.”

Other previously existing custom user roles are showing in the list, but not this one. For example, a custom role created by Woo Commerce, called Shop Manager, shows, and a custom role created by Event Espresso, called Events Administrator, shows. However, after using the “Members” plugin to clone the “Editor” role to create a new role called “National Board” — and assigning the board members to it — the new role shows up everywhere except in the dropdown for the Participants Database plugin’s Settings > Admin Settings areas.

Anyone have any ideas?
