BPS Geometry Curved Stairs - limitations? Workaround?

So, the BPs curved stairs - two issues.

1: I cannot go higher than 100 (Of course you can alt drag)
2: The height gets messed up real fast
2a: How to get rid of the space between steps - without changing the height of each stair? (Shown in picture)
2b: The above also affects my guy having to jump vs run (even if I get the space worked out, as the height is too much even when solid)

Thanks… really enjoying UE4 so far - especially playing with the BPS Geometry tools to see what can be built and not…
