[Forminator] Issue with select height and conditional logic

I have 2 issues with Forminator forms:

#1 I have a few selects which have an empty option selected by default. To create empty option I’ve typed space in the option label, as a blank option not allowed. Because of this the selects are collapsed and thin vertically.

Is there any way to prevent this?

#2 I’ve added conditional logic to my selects, so only one of them is showing up with depends on which of the radio buttons is selected. But for some reason, when you go to click a different radio button to the one highlighted, it starts showing multiple options, instead of just the one.
