Whether Will becomes redundant if not opted for enforcement before otherwise mutation of the propert

My father (A) died in 2016, leaving behind two surviving adult sons (B & C) and two surviving adult married off daughters (D & E ). My mother had expired in 2005. So, B, C, D, & E became the legal heirs of A. My father A owned self acquired immovable property comprising land and residential building which he had bequeathed to his two sons B & C by an unregistered ( but notarized) Will dated in 2009 and same was in custody of B & C. After A's demise, the beneficiaries i. e. B & C preferred not to produce the Will and seek probate. Instead, along with D & E, they applied for mutation of the property jointly in the names of B, C, D & E and in 2017, the said property was mutated jointly in the names of B, C, D & E. All along, D & E were not given any information about existence of any Will. After mutation, the ground rent receipts also began to be issued in joint names of B, C, D & E. In late 2018, B & C, produced the said Will and filed a probate case in the competent court, without disclosing in their petition anything about the mutation of the property taken place in 2017. The case is in progress. My question is - When the beneficiaries named in the Will have, by their own active consent preferred to get the property mutated in the names of all four legal heirs of A, in the given circumstances, whether the Will becomes redundant ? Moreover after mutation, the property now stood in the joint names of the legal heirs and so even if any probate is granted what will be its effectiveness for execution as the property no more stood in the name of A in all records?
