New Tactics Trainer (unrated) Fails At Retrying Puzzles

So I just tested unrated mode for puzzles of themes I have failed at in the past, and noticed that when clicking the retry button, nothing happens in this new mode. Even though there's no good reason for solving the same tactic again, I like to go back to the initial position to go through all the steps in my mind for achieving the result. I know, I can always go inside of the analysis, but retrying is a feature here, so why doesn't it work? Just curious to see if this is just happening to me, or if everyone has this issue.

Oh, thanks for the report! Could you please give us the exact steps you follow so as we can reproduce? Thank you so much!

No worries. I was able to reproduce.

Good  Sorry for not including the steps, but thought it was kind of straight forward. 

True that.
