weird button in test

hello I have attached two photos. One shows what it looks like after I have guessed a flashcard. At that point I have set the test to allow me to toggle various dictionaries. However on the toggle bar there is a little "undo" type arrow (I have pointed to it with my red arrow on the second pic) Does anyone know what that does? It only appears after you toggle dictionaries. I don't want to press it because I am afraid it will mess something up.. Thank you

Hi Forrest,

no worries, that button will toggle the dictionary back to the very first dictionary that was shown for the card.

Cheers,

It's a minor bug that the "go back" button will still appear even if you manually cycle back to the original dictionary, which can make you think it's not the one selected.
