Unable to delete kata(or draft) created from kumite

[10XL]

I created a kumite and converted it to a kata. I've done this twice(two separate kumites, same code). When I press delete, the loading spinner/bar doesn't ever stop/finish and I'm given an error;

Same error for both, except for the id's.
