Appointments Services column missing

After updating to the latest version of Appointments+, the "Name" column in the Services section has disappeared, and there is no checkbox in Screen Options for that particular column. If I revert back to the previous version, the column re-appears.

Somehow the header and table rows in that column have inherited the .hidden attribute in this version and thus inherit display:none; in the CSS.

I've fixed the issue temporarily by adding a bit of CSS to Admin CSS in Ultimate Branding to override that, but can someone please check to see why this has happened?
