Deleted Beneficiaries

We are instructed in a Probate matter where we obtained a Grant of Probate where Testator had made lots of handwritten amendments in her will on her death bed and got it re-executed by lay people. (not doctors or lawyers) After filing affidavits by witnesses The Grant was issued. My research shows that the beneficiaries who were removed can bring a claim as to the validity of the will and that there is no time limit for this. It’s a substantial estate. Should we inform the beneficiaries who were left out and see what they want to do or let sleeping dogs lie? How do we protect the executor, the new beneficiary ( a charity) from future claims and of course ourselves. One of the witnesses works for the charity who benefited although there is no sign of undue influence this could be alleged.
