My mvm bots arn't spawning

[StoreMilk]

I'm trying to figure out how to get an mvm game working to make mvm maps. I have made a very simple map and have gotten the pop file to load properly and generated a nav mesh, but the bots are not spawning in the game.
I have an error in the ingame console that says it cant find the entity "wave_start_relay", but i cant find anything on that. Could someone please take a look at my vmf and help me out?

I haven't made maps for MvM, but try opening readme at Steam/steamapps/common/sourcesdk_content/tf/mvm, And compare them, maybe you forgot to add something.

I got it working, I don't remember how

Probably bot naming or something in the pop file
