[NEED HELP] Mod overriding vanilla Xonotic

I have recently played several games on the INFRAAGH mod servers. Now when I play on any server those settings override my vanilla settings, even when I close the game out, reboot pc, etc, I now have no announcer, except for telling me time remaining, and I cannot hear opponent damage sounds. etc. It makes for a very boring game. Please help. I have always had temporary mod carry overs, like switching from Jeff's Resurrection server to another vanilla server, but nothing permanent ,until now. Someone on a server told me to clear the game cache, but did not explain how. Any help would be greatly appreciated. Thanks!

You can find the folder with files downloaded from servers under ~\USERNAME\Saved Games\xonotic\data\dlcache
You can try to delete all files inside dlcache.
