Can I Remove Fingerprints Via the App?

I have a U-tec UBolt Pro Series. I have had several guests try their fingerprints and access our house without being added to the app. As a result, I am trying to remove all fingerprints from the app, so that there are no longer any false positives. But for some reason, when I navigate to the user and click their fingerprint, it only lets me add them. How do I remove user’s fingerprints?
