Multiple Choice Problem On Iphone

I added this CSS code which seems to make it work but the selection is barely visible on my iPhone.

.wpforms-container input[type=checkbox] {
-webkit-appearance: checkbox !important;
-moz-appearance: checkbox !important;
appearance: checkbox !important;
}

This is the one built with wpforms – if you look at the iPhone view you will see the issues

This is the same form built with contact form 7 which is working as it should with Yes/No selection visible
