Can a property be put on holdwithout filing a partition deed?

We have a property having 5 floors, my grandfather has gifted the entire ground floor to my father(gift deed is registered), also he had gifted the entire first floor as well but now after my grandfather's death we came to know that there was a typing mistake in the deed. All of the pages of the deed say entire forst floor except one point where it is inadvertently mentioned half share of entire first floor. Though the stamp duty has been fully paid. Now when we want to sell our ground floor my father's siblings are threatening to put a stay on the entire building. Would we not be able to sell it? Also, please advise what can we do to get the typing mistake rectified.
