Form Designer had overriden a lot of layout and made all input fields have same width

. I opened
the 'Beta' form designer and it has overidden alot of layout... EG, made
all the input fields the same width, and I need them to be custom sizes. Is
there a way to undo this? When I try to edit the width of the custom fields
now, nothing happens

You can delete all the CSS from 'Inject Custom CSS' section in order to get the standard layout.

Alternatively, you might try reverting the form to some previous version:
