Hustle widget colors won't change, but now layout is messed up...?

So here is a strange issue...

I had a Hustle widget set up and I liked the layout - the name & email fields and the text button were all on one line. Nice and compact.

I edited the optin to change the colors. The *only* changes I made were to the colors.

Upon refresh, and even when browsing incognito, the colors have not changed. But now the submit button is broken to a line below the name & email fields, rather than the same line.

I'm really confused as to why the colors have not changed but the layout has. I've tried adding both using the widget and the shortcode and both yield the same results.
