25+5 Timer won't pass tests

Hi all, My timer appears to work as needed, the UI is hideous at the moment but my main goal is to make it function. There are a few tests, specifically 12 13 and 15, that are giving me very confusing errors. https://codepen.io/seth-alan-burleson/pen/jOMWrjP?editors=0011

As far as I can tell, the clock functions correctly, but the script says otherwise.

Can anyone help me out with this?

all of your tests pass
