Using FF browser extension but not grabbing website that I have regexed

I have a regex set up to grab Reddit site usage. However, in summary under Top Window Titles because the Reddit page doesn’t include an exact match, those pages are being thrown in Uncategorized but Reddit is being tracked under Browser Domains.

I’m trying to understand if that means that reddit.com/pagea is being tracked twice. Once under Uncategorized and again under the reddit category I created?
