This very thing happened to me with a 2 compartment insert I ordered from B&H for the F2 / F1x sized bags. Not only was it smaller than the old two compartment insert, it was also smaller (in width) than the newer design (with adjustable panels) Digital insert that I have. I sent mine back for an exchange thinking it may have been a defect. The one I got in exchange was larger, but still a bit smaller than I figured. Works OK though. Like you, that first one I got was really unusable for my needs. It was about 1/2" narrower in width than it should have been. B&H was excellent about the return. They sent a pre-paid shipping label and turnaround for the exchange was very fast.
