Referrrer type missing numbers for unique visitor and visits

There are 2 things that I notice here...

First, are you tracking your Mobile Apps into the same suite? Mobile App don't trigger referrers, so that could be one difference between your UVs and your UV Referrer Types...

The other thing is, if the referrer is potentially sending some garbage data that Adobe can't understand, it's possible that this information is stripped out from the final results that show here...

You might need to look into the raw data to try and dig deeper into the discrepancy.

Consider these troubleshooting steps:

1. Data Collection: Ensure the tracking code is correctly implemented and free of JavaScript errors.
2. Processing Rules: Verify that processing rules and referrer configurations are correctly set up.
3. Traffic Filtering: Check internal and bot filtering settings to ensure they aren't excluding legitimate traffic.

Try breaking out by referrer instead of referrer type.  See if you get similar values.  When I broke out by referrer type I don't see typed/bookmarked.  When I broke out by referrer, the overall total was the same.  Those without a referrer also didn't have a referrer type.
