Kodi working in entities , but disappearing from gui

Hi Everyone,

I’m a novice HA user, familiar with the configurations and other stuff, but now I face with a strange problem: I have 2 Kodi players: one right on the RPi3 with the HA installed, other one in the same network with RPi.

Problem: Kodi state and controls not showing up on the frontend, but the state and details are showing up in the entities list.
BUT: If I change something in the configuration.yaml (for ex.: I add them to a group), they show up temporary. If I click on other menu entry, then click back to overview, they disappear again.

Any touhgts are welcome!
