Accessibility Issue with Smartcrawl

Hi,
There is an accessibility issue on Smartcrawl when you have high contrast mode on in Windows 10 and using the latest version of firefox.

I have support access on for nfbga.org. Go to smartcrawl settings > import/export > Yoast seo

On the page it asks you to choose what you want to import but you cannot tell what state the buttons/checkbox is in.
