Enabling/Disabling weapon packs 1 and 10

[Alejandrez]

I want to play without pack 10, but If I try to disable it, pack 1 also disables. If I enable pack 1 again, pack 10 becomes enabled too. I tried to log out/in and refreshing the browser several times, but it keeps happening and I tried in other accounts and also happens. I would want play with pack 1 again, in the settings I usually play it is so useful, but pack 10 is not, fix it please
