Multiple iterations of the same gear

I have two sets of identical ilevel 340 shoulders in my possession and AMR has them as my current BiB items for both my main and off specs. I have them both locked with the azerite traits I want in game but the website, when uploading to the addon, always selects the wrong shoulders for the gear set and tells me to reforge the powers on them. I did this once to see if it was just maybe logging them as a different number but once I had the new traits locked in, returned to the website, entered the string from my addon, ran BiB again and reexported the new string to my addon it did the exact same thing with reversing the pieces. I have tried multiple ways to try to fix this but nothing seems to work so anything you guys could recommend would be helpful.

Could you post your export from the addon so that we can take a look?
