Event Fees not loading when registering in back-end
Recently upgraded a site to 5.2.1 in WordPress 4.9.6. When the user tries to register a event participant in the back-end the fee selections price set does not load after the event is selected. All works fine on front end pages and if you edit an existing registration you are able to change the fee selections.
Checked another site with the same setup and the results are the same.
The results are the same if you try from the contact record either using the register button or the submit CC payment with registration button.
