Sims Free Play Bug

I recently had to delete and reinstall the Sims freeplay on my kindle Because I was noticing That it wasn't selling The home The home decor, And I wasn't able to compete in any of the challenges. However when I reinstall the game I noticed that there is a lot of bugs where I can't see my houses clearly.  My houses are missing Furniture The lamb the grass is showing up as completely white. How do I fix this?
