~です ~ます questions

Hi,

I got stuck in a constant loop of ~です ~ます which I appear to be entering wrong.

There are about 6/8 selectable options. Containing things like ~です ~ます ~する and other words. However I click ~desu and ~masu in that order, then next, and it looks like I get it right? But it repeats the same thing a crazy number of times.

Then when you click ‘show answer’ it just describes ~desu and ~masu.
I feel like an idiot haha, but how do I answer this question?

Try now.

Still broken?
