Greyed out linked record field

Someone has just reported an odd bug to me, where if you go to create a record from a related record collection, change your mind and then click to the collection page (either from breadcrumb or nav bar) and go to add a record there, it leaves the linked record field as disabled so it is no longer selectable…

For context as the above sounds confusing…

We have a collection called applications and a collection called documents. They have a many-to-many relationship.

From the application page there is a collection of related documents, if you start adding a new document from this collection it automatically links the application and disables the field which is fine


but if the user then navigates to the “Documents” page without saving this and then clicks to create a new document, the applications field is left empty but still disabled:
