Moving left and right not working as expected. Please help

Ok... Ive been working on getting this working for about 2 hours now, and it is as far as im concerned its working entirely other than ONE thing...

The problem, is that, when my player is in the air and they move right and collide with a wall they simply collide. Simple.

But when the player is moving left and more commonly left and down, or left straight after falling off a ledge. And hitting a wall, they will almost always, for some reason, become grounded.

What is confusing me is that the left and right move scripts are exactly the same, with a few variables changed so that they are designed to go in opposite directions. My grounded check is also, centered, so i dont imagine it could be happening to left due to it being offset.

If anyone could help i would greatly appreciate it! Here is the script: (sorry but unity wont let me make a code box for some reason )
