[Pro version] Translate All Categories

Hello! I would like to change the text All Categories (The swedish translation on the page is ALLA Kategorier) to something different. In the Pro version I can only find the translation for the text All. Else I would like to remove that whole sentence so the first category shows up instead (which is ALLA=All). I also use etiquettes/labels for multiple taxonomy filter and I have hidden that with css. I can’t find how to hide also the second taxonomy. Thank you for help!
