OMG,
This situation is typically for hydraulic rams, which operate with different speeds on both sides. Maybe a result of "roof violence", defect of the hydraulic pump after massive water ingress and so on.

Which hose did you repair with this coupler?
On your pics it's one into the roof shell, isn't it?
