I have same issue with firestore UI web panel tho I found a solution using cloud.

First you need to enter https://console.cloud.google.com/ and select your project after that open gcloud terminal (you can access this on the top right corner nearby your avatar).

To list all your composite indexes for selected project, type this into the terminal

gcloud firestore indexes composite list

Then pick id of the one you want to remove and type

gcloud firestore indexes composite delete <composite-id>

It'll ask you for confirmation, once you done it by typing and entering y your index is gone c:

In the Cloud Firestore UI web panel, the icon with 3 vertical dots is for some reason hidden. If you hover over the right part of the line, just right to the status field, the 3 vertical dots icon will show and hovering over that will show an option to delete the composite index for a collection.
