Hi, I have a weird issue..
My user meta fields which allow selection of different users are not saving correctly.
So it saves, because the user is there. But you need to save a second time to make it work with the value. Until it is saved a second time, it does not output, nor show in the meta from the WP backend. It shows as null.
Do you have any idea what this issue is, and even better - how to fix it?
I disabled all my custom code to ensure was not that.
