First camera character does not seem to jump high enough to go to next staircase step

Hello. Actor does not seem to be able to jump up on a long staircase I made. It jumps down fine but not up enough to make it to the next step. I think it is not jumping high enough. Using the first camera blueprint. this is my very first project ever, totally new at this. I looked at blueprints of camera and gun but cannot find where to change, adjust or fix. how do I know how high the first person char can jump? My staircase is not huge so I am totally baffled. I am using the space bar to jump. I saw another post about adjusting this height but it was for the third person BP.
Thanks for a response.

This is in the character movement (Jump Velocity will result in a higher jump).
