I have the same issue. It shows visits to particular adset names but then the majority of visits is to the {tokens}
This is a Facebook dynamic parameter, right?
If so, I have some bad news - looks like they don't work properly for everyone.
The problem isn't on
Not much you can do at the moment, from what I understand - replace the token with the name of the adsets manually in your FB URLs to get accurate tracking.
You could try square brackets instead of double curly brackets - apparently that works for some people on some parameters - but otherwise, come back and try them again in a month and see if FB's fixed them 
@caurmen is practically doing our job! Kudos to you 
Due to the FB documentation, they are supporting this token. However, it happens that they are returning us this dynamic token instead of replacing it with actual data.
This mistake is on their side, and we don't really have any info on it being solved in the nearest future or not. Therefore, the best thing to do at the moment is contacting FB Support and trying to figure it out with them.
