Cannot Fill In Field

Hi,

My company has recently updated our WordPress, and now we are not able to fill in one of custom fields. We had created categories for manufacturers of our products, and the field originally created would auto-populate the names of companies as you type. After the update, it no longer does that and we also can’t click “View all manufacturers” as when you click, nothing happens. Would really appreciate assistance on this!

Thank you,

Chloe
