Can’t update custom post type taxonomies

Hi,

Just as a reference I’ve just a custom post type called “Job”

After the latest WordPress update I can no longer update a posts custom taxonomies. After clicking the update button it doesn’t save the new taxonomies I’ve added to the “Job”. However if I create a new “Job” it saves the initial taxonomies.

I’ve tried deactivating Polylang and I can then update them, meaning I believe the bug to be with Polylang.

The strange part is that the bug is only present in production and not locally, locally it works fine even though the set ups are the same.

Any help is greatly appreciated!
