Why do I keep getting the same 3 maps?

I just started playing halo again and the past month I’ve been playing in social matchmaking I’ll only be dropped into the same 3 maps…the Coliseum the map with the sword up in the middle of the map (cant remember the name) and the one that looks like it’s set in a parking garage/warehouse.
Its really frustrating. I would like to play one of the other many maps.

Is there any solution or am I just stuck with these 3?

It’s because you’re playing Quick Play. This mode only features those 3 maps that you mentioned.
