Good afternoon Natasha,
I am glad you got things working to your liking, regardless of what the cause of your success is 🙂
As far as you other question is concerned, I will ask our coding Ninjas.
But, in the meantime, you could totally cheat with CSS.
Try adding the following CSS rule to your style.css file or in your Custom CSS metabox:
#tribe-community-events .recurrence-row {display: none !important}
Let me know how that goes.
Best regards,
Geoff B.
