Hi, Yes, the Bridles should be tied together at the loops at the top middle of wing.
If you can possibly call me with the kite infront of you, I can talk you through it quickly.
I believe there is also a tutorial video, by Watty that shows how to tie the bridles together.
Feed the long loop ( on the horizontal bridle) through the small loop ( on the vertical bridle) about half way.
Fold long loop back on itself and feed down through the long loop. Pull tight.
Same on left as on the right.
