Organizing Check box fields

Im using several check boxes in a form:

But when I select them at random order they don’t show us nicely in my PDF preview

Here is the way its been organized in my form setup.

It seems its trying to create a middle horizontal alignment. Is there a way to align it better so it doesnt seem unorganized?

Or show them always, and when selected showing a v and when not a -?

Thanks,
Rutger
