Hi Paul,
That’s not an issue we’re aware of. Have you tried disabling all other plugins to see if there might be a conflict?
On the excluding categories – there’s not currently any way to do this in the admin but we do have this on the roadmap. In the interim you can easily hide categories with CSS like so:
#event-categories #tribe_events_cat-4,
#event-categories #tribe_events_cat-5 {
display: none;
}
I hope that helps! Let me know if deactivating other plugins works for the saving categories issue 🙂
Cheers,
Jonah
