Synced entitiy from HA to Alexa via Nabu Casa looks for Node Red server

Created simple script in HA that control a media player volume. Works from HA. When sync the entities via the cloud options in Nabu Casa it works at first. After a while it stops working and when I check thru the Alexa app, I see that the synced script (which is now a device in Alexa) is waiting for Node Red server (even though the script is not related to any node-red flow). What can cause the device to change from HA to Node-Red in Alexa?
