SO MANY ISSUES/BUGS

The first snapshot shows the "No textures issue on the Store." The City Texture Pack and the Plastic Texture Pack has no picture. The second snapshot shows the "No Steve and Alex picture issue". The Steve and Alex skin can be equipped,but when you enter the skins section,you will see no pictures of Steve and Alex. The third snapshot shows the "No hand/item appearance bug". This happens to me when I reopen MCPE and reopen a world. Please fix all of this issues that I reported. These are so annoying to me and other players. We will really appreciate your work.
