Removing "Please select" from dropdown

Hi,

In my account I have a Test covid form & a Daily screening form.
I don't understand why in one the dropdown lists do not show a "Please Select" while the other form does. Yet in the properties, etc. they both appear to be the same.

You can remove that using this CSS code:

select > option[value=""] {
display: none;
}

Please give it a try and let us know how it goes.
