Cisco 3850/IP Base/IOS XE 3.7.2

I was going over my NetFlow data, and it seemed I was only catching flow in, and not out. I already had the in/out records and monitors, using the same exporter to one sensor in the monitoring suite. I set up another sensor on the monitoring software, using the next numerical port. It worked as intended for about 5 minutes, then stopped transmitting.

What am I missing here? the In exporter is using 2055, the Out using 2056. This was done to allow separate sensors in software. It *did* work for a few minutes and then it quit. There definitely seems to be a change, as the still working NetFlow sensor shows highly reduced traffic.
