Try clicking on the little grey dot on the right and dragging it to the left. It is weird though that the settings window shows like this, in mine I can alter the width of the column with the grey dot as mentioned, but the input fields remain visible all the time.
I had this issue as well but it seems to have resolved it’s self. Might have fixed it’s self when I restarted the machine. I’m not sure. It wasn’t working yesterday and when I checked this morning it was.
