The issue I am facing:
Local DNS >> CNAME - Unable to remove entries
Details about my system:
Pi-hole [v5.2]
Web Interface [v5.2]
FTL [v5.3.1]
What I have changed since installing Pi-hole:
This is first time adding entries in Local DNS >> CNAME and unable to remove them. Tried clearing browser cache. Tried different browser. Same thing.
I even tried restoring from backup. It wouldn't even clear them.

I perfectly agree. The CNAME editing page was an external contribution and, apparently, we haven't checked it carefully enough to recognize the missing/incorrectly working validation. On the Todo list.
