Really Annoying Bug

I've taken to placing all tasks in "pending" right now, as I cannot delete or edit any of them (I really just need to delete them). Whenever I go to edit, if I click anywhere except "save changes" the screen just closes. I've been relying on WeekAp for several months now and I have a bunch of completed goals I cannot get rid of. This started after I clicked "Yes" for a screen that asked me if I wanted to start using a new version. Anyway to switch to the old version? Is this just me? I tried it in a different browser and the same thing happened.
