Another option could be to have 4 buttons at the bottom of a Kata(Reset, Run Sample Tests, Attempt) -> when a user has solved the kata and 'Attempt' turns to 'Submit final solution' to the left of this another button could appear 'Re Run Random Tests' to more thoroughly check your code, rather than not getting to test your code again.

I'd like the option to delete my solutions and consequently lose the experience for that action.
Reason being, I've being doing a Kata and when I test my solution vs the random test cases, my solution sometimes passes, I have since found
the bug in my code to why this is, however my code has been submitted x number of times without me knowing(I tried to go back/refresh to test my code against the random test cases again(so it passes every time) but think it kept submitting. Now left with a few solutions(messy) Is there a way to clear these up?

Any help would be appreciated.

You cannot put an "issue" when you want somebody's help. "Issues" are for problems in the kata itself. There are no errors in the tests. Please post it as a question.
