DLC maps not downloaded error

Hi, I’m relatively new to t7x client, sorry if this is already mentioned somewhere in installation guides. Whenever I try to join a server that’s hosting on DLC maps such as, skyjacked, spire, splash, or any other map that isn’t in the default category. (Minus nuketown and night fringe, snowy redwoods) The exact error I get states “Can’t find usermap: mp_skyjacked! Make sure you’re subscribed to the workshop item.” or “The server loaded a new map, and you do not have the map installed yet.” Please give me any advice you can. Thanks in advanced.
