This is what I was getting at.. the fwd pair might be different lengths than the aft pair, and someone mixed up one of each.... could explain your issue, esp if the other turnbuckles seem in normal mid range adjustments when the mast is straight and centered.
A few hours of a rigger's time will likely be a good investment, for peace of mind if nothing else..
