Your radius for the monuments is set at 1000, which is insanely large. You can check to see if there are any bots spawning somewhere on your map that you can't see by going to the console and entering "bot.count" without quotes. If you, in fact, do have bots spawning but you can't see them, try lowering your radius to something that fits those monuments. Roadside monuments, like Supermarket or Gas Station should be about 20-40, while larger ones like Water Treatment and Power Plant should be more like 60-70. You currently have a radius of 1000 for the Abandoned Cabins, which the monument itself is only about 100 in size. Adjust your spawning radius accordingly and see if that helps.
