While taking a look at this issue: https://kagifeedback.org/d/6722-lenses-working-incorrectly, there was a lense shared: https://kagi.com/lenses/AkWUsQ4GDAytwwgZjuwtm47uFPmktPTO
Deleting the lens doesn't delete it from the "Active Lenses" list
After some playing around with the on and off toggle, I was able to finally remove it.
I expect a lens, when deleted, to be deleted from either "Active Lenses" or "Other Lenses" list
