I have errors trying to get into some maps like swag_multigames whenever I load it I get stuck at the loading screen for ages:

The error I get is:
ApplyGameSettings: Map mg_swag_multigames_v5 not part of Mapgroup
ApplyGameSettings: MapGroup not part of type custom mode custom
Executing server command:
nextlevel mg_swag_multigames_v5
map mg_swag_multigames_v5 reserved


And I don't know how to add maps into the custom gamemode mapgroups

// Map groups

// To use a mapgroup, it needs to be defined in a keyvalues
// block such as the example below, as well as listed in the 
// 'mapgroupsMP' block within the game mode that will run it,
// such as the example above.
//
// Then launch the server with '+mapgroup MAPGROUPNAME'
//
// Example:
//
// srcds -game csgo +game_mode 1 +mapgroup mg_bomb_se +map de_nuke_se
