It looks like the derivation path is different from the 2
M/84'/0'/0' for Sparrow M/44'/0'/0' for Blue Wallet
You can go to settings in the wallet and change the derivation path if you hit the replace button, re enter the seed and after you comfirm the seed you can change the 84 to 44
I wish that would have worked. still messing with it. I found someone on Reddit that says "the issue is Blue Wallet changed the script to Legacy and is showing the wrong derivation path. Change the script to Legacy but keep the derivation path your original m/84/0/0
