How do I get rid of Kobold?!

I installed Kobold, attempting to make an alarm clock in HA. I couldn't get it to work at the time, later my desire to have a clock in HA changed, and I removed Kobold. Ever since, editing the dashboards, I constantly get errors that it can't find Kobold. I checked high and low in my dashboards, in every yaml file I can find, I can't find any reference to Kobold. How do I get it to stop popping this error when I'm trying to edit?! It's removed! The dash I tried it on is long gone!
