The label says "Sangle wide" - it seems that it is a newer model where the straps are wider but shorter. If the purchaser had a chance to see and try it before the purchase, it is more of a change of heart (buyer's remorse?) or oversight, not H's manufacturing defect.
BTW, I would love to have these wider and shorter straps for my TPM. I bought mine at the FSH back in 2012. At that time, the straps are all leather but very long and not removeable. It is kind of too long as a cross-body bag for me, but as the straps are not removeable, there is nothing that I can do about it. At least for the newer models, the straps for the TPM can be removed and replaced.
