G'day everyone

Am checking the lines on my north 2014 trust bar for the first time in a while and have noticed the supposed to be unloaded fifth line is shorter than the two fronts like in the top pic.
The thing is theres no place to lengthen the line till below the red stopper (pic beolw) which is already hard up against the ring, so lengthening it at the red line in pic bottom two only creates more slack below the ring and in my head I'm flying the kite with a loaded toppart of the fifth line and unloaded bottom part.
Is this a case of buying a little line extension for the fifth line, a whole new top part of the fifth, or am I a complete knumpty and have missed the point somewhere else that I could adjust for this.
Thanks for any advice I've got serious KOD and nelson bay could be on today.
