Why does one of my validation input switch to dense when it's validated?

I have a two input fields which I validate separately with an action on a button, however once I validate one of the fields seems to switch to dense.

Since my second form field has a few more bells and whistles to it I have tried to wrap the entire stack in the validation widget, I've tried to wrap my form field in a container and set the height, however nothing seems to work.

Does anyone know if this is fixable?
