Hi Najib, are you referring to a button? It might be that this button is cached and does not refresh. Hitting either ctrl+f5 (Windows) or cmd+shift+r (Apple) should clear that.
If you're not referring to a button, could you perhaps send me a screenshot which shows it being stuck at 777. You can find my email by hitting the Contact link at the bottom of the page.
I can tell you that we're seeing your button being at 780 over here.
