Hi Deb
I must admit to being a little confused by some of your post. Who told you that ONSs were suspended? (to my knowledge, they never have been).
You are correct in that tags are not showing up on profiles: they won't show up unless you put them there ;)
One reason the tags on your Name Study are not showing up is that you need to put ONE surname per tag. So your tag that starts Cashia, Cashie, Casie... will not work because there are 11 surnames in one tag. So you will need to make three tags: Caziah, Casiah, and Kizziah, which will mean removing that long one and the one which I think is in Cyrillic script.
While you are at it, please move all that text from the category page
https://www.wikitree.com/wiki/Category:Caziah_Name_Study
Category pages should have one or two brief sentences so you know where you are - and the categories themselves. Something like:
"This is the companion category page for the [[Space:Trew Name Study|Trew Name Study]] and includes other spelling variations. To add this category to a profile, you can add the One Name Study sticker (which will add the category automatically)."
The rest should go either on its own separate freespace page (linked to the main Study page), or on the Study page itself.
You can reach the companion category page by clicking on the phrase 'Caziah Name Study' among the categories at the foot of the page. This is a list of all the profiles you include in your Study.
Your category will be [[Category:Caziah Name Study]]
and your sticker will be {{One Name Study|name=Caziah}}
and living members of your Study will be able to put {{Member|ONS|name=Caziah}} on their own profiles
