If you are comfortable posting your xpubkey then I can confirm that your "original" wallet in fact has the small amount of bitcoin. Although publishing your xpubkey will cause every transaction that you ever made with that wallet (seed) to be made public, both transactions in the past, and transaction in the future.
I recommend you to use https://www.blockonomics.co/ to look for your balance. If you find your total balance as zero, then go to bottom and click 'Transactions' and see if it shows any transactions. If not, then your xpub is different.
