Could you share an example (link to a figma file with the form fields that misbehave on autolayout) or a more detailed description of what you’re trying to do?
They’re not jumbled, they’re just automatically laid out vertically, aligned to the right, with no vertical spacing between them. To get the overall layout you want, you’ll need set up auto layout to manage both the horizontal layout of the fields that should sit in the same row, and then also auto layout to manage the vertical layout of the rows.
I made a short video to explain what I think is happening and one way you could get the layout you want.
