Tracks and top hinges are generally adjustable to fit the door reasonably
close but the older doors often do not fit very well. You will probably
need
to install some weatherstripping.

Do you mean the hinge between door sections, or the large guide with 2
rollers attached to the right/left top corners of the door?

It seems that this large hinging guide would apply pressure to the door, but
it's not pushing against the track in that position. Tried to find a
picture of it on the web, but could not. They are sold in all the hardware
stores.
