if it's repeating the text content, we shouldn't need control text (though, worth verifying with a screen reader).

I've tested these changes in NVDA & Voiceover, there's no repeat, the changes here just ensure the done and reset buttons have the correct text. Previously the done button had the same text as the reset button, which was misleading.
