Accommodate >11 covariates for vaults

[spanta28]

The vaults currently give issues if there are >11 covariates.. Check out the screenshots.

You can come up with a good UI way to do this , like may be have a slider to the right of the covariates section so that user can slide down the variables and also indicate how many variables there are , like put that placeholder for that number somewhere above that section so that user knows how many there are and he knows to scroll down.
