For some reason my Pause Panel appears on the same layer as my Start Scene canvas even though the Z positions are different for both. Tried messing with the hierarchy but no luck.
One workaround I can think of is to just disable the few gameObjects that are coming in the way, but I’m sure there a better way to do it.
wont u disactive your start menu when the game is runing ? 
any way u can change a canvas order , it has its own sor order witch u can find in its component ,
