Dear larryL ,
1. You added 2 fields shortcodes (wpv-post-field name="wpcf-support-documents" and types field="support-documents") it's why page showing documents twice
2. I've added new class for each document item and small JS for cred. JS replace url to file name. You can play with this if you need customize it.
Please let me know if you are satisfied with my answer and if I can help you with any other questions you might have.
Regards,
Gen.
