PowerBI App Navigation panel Bug

I have a navigation bar in my PBI App.In NAvigation Bar i have a created a section called FS COMMON. Under this section i have added Reports  FS Allocation, FS MKT & Business Promotion,FS Call Center etc etc.
The Reports marked in the attached image is a single page report(No hidden pages).When i open the App i could see an expand button for these reports eventhough there is nothing to expand.

Once i click on expand button, nathing happens and the button disappears. 

Is it possible to fix this bug, as new users think there is some page missing for them, as the expand button is visible and upon clicking it nothing happens.
