I have just now (8:40 a.m., central) learned of an earlier text from Fr. Paul Kramer that discusses the Fr. Ingo Dollinger claim.
I shall accordingly update chapter 12 of On the Third Part of the Secret of Fátima. I was unaware of this earlier text while writing my book and offer my sincerest apologies to readers. These discussions on Fátima are ongoing and so we learn (and update) as we go!
