invisible minecarts

Minecarts dissapearing randomly

*What I expected to happen was a minecart appearing but it became invisible and I can only see the shadow of it

*What actually happened was that it was visible at first then I accidentally touched the homescreen but the app did not close so I went back to the app again and then the minecarts disappeared. However it became visible when I closed it and opened it again but sometimes I have to do that multiple times just to make it reapear again.I have a screenshot showing the invisible minecart shadow.
