Tags showing on site even though items aren’t public?

Hi,

I’m using Omeka Classic and I don’t want my items to be publicly viewable yet because I’m holding off until my book is published. I’ve made sure the items themselves aren’t marked as public.

However, I just noticed that the tags I’ve added to these private items are still showing up on the public site. Is there a way to stop this from happening?

Any suggestions or fixes would be much appreciated!
