NTA server does not show all flows in Web Console

Hello everyone!!! I'm new to SolarWinds products. Our company decided to deploy network traffic monitoring system. Our choice was on SolarWinds NTA. I deployed NTA trial environment and configured Netflow on network devices. NTA server collects and shows some data from network devices but not all. Wireshark on NTA server shown me that  network devices send all neccesary flows to NTA server, but it does not show me them in Web Console. What's may be wrong?
