I see it this way, say your folks and siblings went for it, meds forms are the same ( as u saw ) and DMP takes a month to send to ND, it goes in their processing and then the file in 2 months - meanwhile you get the meds request within a month so they would be technically expecting it anyways, now would they see it was the date they sent you the bulk email vs the date your folks went for DMP ( highly unlikely )
Let Delhi process as per their timeline but bottom like is, these are required anyways
