Not able to modify stair height

[adrianasofiasm_]

Hello!

I used to be able to modify the stair height to what I needed, but all of a sudden it's grayed out and I can't adjust it. I'm not even sure I pressed anything out of the ordinary. How can I unfreeze this setting? 

Thanks.

1. Unlink the Top Storey,

or

2. adjust the Top Storey offset with whatever dimension it needs to be.

Thanks Gerry! I unlinked the top story and was able to modify length.
