Halio Plugin CSS

Hello,

Just installed the Halio booking plugin app.
Support from CodeCanyon has been ended for 1 year, so I can’t contact the seller about my issue. Hope someone here can help me out are change it for me.

If you go to the webpage, you see the Booking form under in first homepage,
The Address bar ( pick up and drop address ) background is color : Black

I would like to change this into White…

I can’t find it somewhere in the CSS file.
