Not showing field when making new post

Updated the plugin to the latest version this morning and then tried to add a new post where a date picker should show up (Offer Ends) but when selecting the category (Current Offers) it does not show up.

My existing posts in the category show the date picker with the date I’d previously selected.

This could go back before this latest update, I haven’t added a new post in this category for some time but it was working before and now it isn’t.

Typically I’m meeting my client today to show him the finished site and then this crops up.
