For some reason i cannot sell items on the auction. When i press the managing button all it does is give me a message that says "Opening", but nothing more?? This is what comes up for me

So, i managed to download the resource pack, but there are some stuff that don't appear to me. For example on the phone, the apps don't show and same with gps, auction. The simple buttons don't appear to me, and i have no clue how to fix it
