Moving to a new PC I jump into this situation:
I bought a new PC and install bisq.
I exported the account from the old PC and imported in the new one (everything was fine)
Afterwords I inserted the 12 words in order to let the
bisq wallet to get the private key and dig into the blockchain to filter out the right balance.
(Wallet seed -> Restore Wallet from words.: + 12 words)
It took some time, but at the end of “sync” it appears a balance > 0 but half in compare to the original balance.
If I run bisq on the old PC I see the right balance (double in comparison with the balance on the new PC)
The date that I see is wallet date is the Unix origin (1 January 1970)
Was my procedure right?
P.S. both version bisq 0.66 and bisq 0.67
