Hello,
Look, you have some kind of server or CDN cache because you have XStore 7.2.2 version installed http://prntscr.com/w4nvww but if you inspect the frontend it still displays the 7.2 version (out of date) http://prntscr.com/w4nxb9
So, once you find out what CDN you use and clear the CDN cache you’ll get the problem fixed. Price will be changed in the top, like here https://gyazo.com/00fd44724b4c0af92055f356e045d8e4
