Unexpected Buddhist Era (B.E.) date for credit card expiry date

Hello,

As my understanding, dates in 1Password are saved in a format set from macOS preferences. But the problem is the expiry date of a credit card is mostly in A.D. format instead of B.E (at least in Thailand is). This causes a warning in 1Password that the credit card is expired as in the below screenshot.

And I cannot save it in B.E. format as well since the autocomplete would be wrong. Do you have any suggestions on this that would keep the expiry date valid along with correctly autocomplete?

Thanks!
