Circle in right middle of the screen

Hello,

I have a Philips tv with Android 5.0 with kodi 16.1

There’s a smal circle at the right site of the screen that appears when i start kodi and does not disappears when i switch to the tv again.

In the circle it shows a picture of a program add on i used of a picture from my library.

Look for this link to the picture Picture

Is there a setting to disable this function?

Regards,

Robert
