Tilemap not displaying on IOS

Hi,
I just recently had the breakthrough of launching my game on the iphone. Now I discover that some of my textures aren’t visible or have an error. The error states to check the power of 2 texture settings. After further investigation a few of my textures were not set up properly to be a power of 2. However after fixing the resolution, they don’t seem to be displaying at all. This is mainly about the tilemap. I am using version 4.12 and IOS version 9.3.2. Please see screenshots to understand what I mean. Thanks
