Twonks were actually migrated from Sigil to 1Sat, but the Ordinals were airdropped to the BSV address, not the Ordinals address, which is not a problem for yourswallet to display because they look in both addresses for Ordinals, but all other platform only check the Ord addresses I guess.
If you restore the wallet in @ZoideNFT there is a notification about "Dirty wallet" that the Ordinals are in your pay address and asking if you want to transfer them to the Ord address.
I only found out about all this when I was trying the same as you did.
