Can't save the description for my watch face

I am trying to write a description for my own watch face through WatchMaker Android app. The more lines you add to the description, the more the "ok" and "cancel" buttons sink and disappear outside the phone screen.

You can write a long and detailed description but you can't save it. And it has nothing to do with the keyboard.

I have OnePlus 7t, I said maybe it has something to do with the notch so I tried to enable the option that hide the notch from the settings but nothing changed.
