Spinning Blue Wheel

Hi all.

I have created a floor plan dashboard and all is working but there is a blue spinning wheel in the middle of the screen and I cannot work out why. It is only on the floorplan dashboard, not on any other dashboards or anywhere else in HA.

Any help is appreciated.

screenshot please?

I worked it out just now. It was because one of the lamps was disconnected. I do have another issue now but I will create a new thread. Thank you
