Hi Tom,
I made another test with ‘author’ role and can not repeat a described issue.
Is it possible to get access to a backup copy of your site (files except wp-content/uploads) and database created with UpdraftPlus plugin?
If Yes, then share .zip with support [at-sign] role-editor.com via DropBox or similar service.
I install and test such copies at my local development environment only.
