Why arent robots coming to station in my roboport?

I want to start replacing robots with legendary versions. I learned that roboports have a logistics request where you can request robots to come and station at your roboport. I have an inserter here to grab them out when they come and a request for 100 bots, and the indicator is yellow so there should be some on the way, but theyre not showing up. The inserter isnt grabbing anything and it doesnt look like bots are coming to station here. What gives? Is it possible there's too many requests going on and this is the lowest priority requests? I have 4k bots and usually have 2k bots active at a time
