PHP - I Found It ,but[showing Array In Phpmysql]

Hello I have an issue with a form that has been built by someone else on Wordpress. 

using contact form 7 plugin there's a for to fill out and it emails a PDF copy to the customer.

however on the pdf any information from dropdown selections shows "Array" instead of what was selected, everything looks fine to me (with my very minimal knowledge of PHP) the title & Preferred Payment Method:  doesn't show on the pdf 

here is the contact form 7 code.
