Deactivated Claim has access to edit/View Listing

Hi there All,

We have a quick one (I think). We accidentally approved a claim to a listing. So we then went into the listing claim and click on the Undo Link. Which then shows the listing as unclaimed. However the person who claimed still has access to edit the post, view the unpublished post and it shows up under there list of yards (listings).

Is there something else we need to do to unverify someone? And to stop them being able to edit the post?

FYI: We set up another dummy listing, went through claim process with new user (temp setup), and indeed after unverifying, we had access to change/upgrade and edit the listing.

We are on WP:4.9.4 GeoDirectory: Version 1.6.25 Claim Listing: Version 1.3.22

Thanks
Simon
