[Feature] [My Fingerprints] Filter for entries with more than 1 value per hash

[JanJastrow]

Is your feature request related to a problem? Please describe.
I just opened up the new "My Fingerprints" page (nice work btw), and found some of my wrongly submitted entries.

I would like to clean this up (delete the longer playtime submission), but I don't wanna go through hundreds of pages :D

Describe the solution you'd like
Add a filter (button) to find entries like this
"Filter for entries with more than 1 value per hash"

Describe alternatives you've considered
🤷‍♂
