How to disable playlist popup in front playing video

Hi,

We have Andriod Box h96pro with Kodi installed. We are using it as a signage system in our shop to continuously play and repeat the videos in the playlist. All the videos are saved on internal storage and all videos added to kodi and then created the playlist. Set the playlist to repeat the videos.

Videos have been playing fine for last 3 days but now after hour or 2 playlist window pops up in front of playing video. so we have to click on it to make it disappear. It is very annoying and also gives bad expression to customers.

We are new to Kodi. Can anyone please help how to make it not show when videos are playing.

Thanks
