Yea I can confirm after a clean import again the wallslide is working Idk why it was not. The dash is working too but I think I found a bug if you dash down like 2 times you lose the dash ability you cant even jump again you need to fall down from where you are standing so you snap out of the state, tried with the keyboard and controller.

The limitation on dashes is delibrate. The player can jump twice by default and theres a limiation on how many times u can dash also. And how far it goes. This can all be adjusted on oEntity create event.
Ill double check tomorrow to ensure that dashing isnt removing a jump. If so its a quick fix. To get jumps or dashes back simply land on ground again.
