Do those without a number have only one?
Do the # disappear in safe mode?
Do you use tag icons to add them? Maybe you didn’t add new tags in the configuration of the component.
All tags that have no number, have no topics associated with them.
You can see that the news-danny-wyatt has a topic associated with it and has no #, but for example I tried adding some of the tags with # to a test topic and that doesn’t change:
At first I thought it was related to some having a tag description, because there was some pattern, but after opening all of them, that’s not the case.
Didn’t know about this feature. Will definitely save it to my notes. Thanks!
That was the issue, yes! 
Thank you so much! 
Since I just use the hashtag symbol, I will probably create a component that does that automatically so I don’t have to think about it when adding new tags.
