Bank and LTO conflict

Hello po, so we have a bit of a problem po regarding our new car that we are supposed to get next week. Sa asawa ko kasi ipapangalan yung car and yung mga pinasa naming loan docs sa bank is yung single name pa nya, although nagpasa rin naman kami ng marriage certificate. Pero sa LTO at that time, kakarenew lang din nya and yung apelyido ko na yung ginamit nya. So ngayon, nirerequest ng dealer na palitan yung nasa LTO portal para imatch sa bank docs namin. In short, ibalik daw sa single name. Tumawag din ako sa bank to confirm what the process should be kasi may nakausap ako na since approved naman na kami and nakapag-DP na and all, baka pwede naman daw na magresubmit na lang kami ng supporting docs such as my wife's ID reflecting her married name and yung marriage certificate para sa part ng bank na lang yung babaguhin. Sa Monday pa daw nila kami mababalikan. Pero ano ba talaga yung pinaka-ok na way to resolve this?
