Media player warning

Hi
I have this warning in my log file.
17-04-17 11:41:53 WARNING (MainThread) [homeassistant.helpers.entity] Update for media_player.stue is already in progress
17-04-17 11:41:53 WARNING (MainThread) [homeassistant.helpers.entity] Update for media_player.kkken is already in Progress

Anyone knows what it Means and what to do? It is referring to my Sonos but they Work fine.

Others have the issue as well. See here 0.41 and sonos update is already in progress error
