I've looked all over for an answer on this, also found a post here about visits higher than Click-throughs, but i couldn't find one that can explain how can i get Unique Visitors higher than Click-throughs.
Sure, so there are no data connectors or data sources, this is s.campaign variable with last touch allocation and an expiration period of 14 days.
The way we populate the campaign TC is by using a url parameter like "cid".
Does this help?
Are you including your entire campaign date range in your report?
One possibility for your issue is that the visitors landed on your site using cid code before your reporting period. However, since your expiration of campaign is 14 days, the campaign value will be persistent for 14 days and when those visitors return to your site without cid code in 14 days time, they will still be included in your campaign report without any clickthroughs associated with them.
Try running the report from the first day of campaign and see if you still get UV > clickthroughs
