Parents are both doctors, bride and groom are doctors (all medical MD).
Is this a strange invitation, names to be filled in properly.
Dr Dad Doctor and Dr Mom Doctor
invite you to the wedding of
Dr Daughter Doctor
to
Dr Groom Doctor
I would not even consider not given the title to the bride even if Emily Post etc say no title for bride, while giving the groom his Dr title.
Somehow it seems a bit much, but still..... these are the titiles.
