Walking onto a box platform from a ramp

Hi all. I’ve only been messing around with Unreal Engine 4 for a few days after checking out some beginner tutorials. I’m trying to figure out how to make my 3rd person perspective starting character walk up a box ramp on to a box platform. I eyeballed the alignment of the ramp and platform, they appear to be very close, but the character won’t get off the ramp to the platform. If I make the platform ground level with Shift-End then he can walk on it without the ramp. Any thoughts? I attached a few images for reference.

Thanks
