I didn't thought to do a rescan..
Thank you for your fast answer guys
Any follow-ups or you'll just leave it unresolved?
If using a 'blockexplorer' doesn't concern you (
privacy concerns), you can lookup that address and see if there's any unspent output(s).
If there's none, then it's indeed Bitcoin Core's issue when it scanned for wallet-related transactions.
e.g:
blockstream.info (
check if it has any "CONFIRMED UNSPENT" outputs).
