Mott's claim was the dossier was "fake", not that everything in it has been confirmed.
Specific incidents in the dossier has been verified and the overall story in it i.e. that the Russian government was trying to help Trump get elected is overwhelmingly proven. The dossier is far from "discredited" no matter how many times you falsely parrot that claim.

The dossier contains false allegations. I don't have to tell you that the credibility of the whole dossier is ruined when there is even one false allegation proven to be false. You know that well, but you are pretending it is irrelevant like no lawyer ever honestly would.
Here is an excerpt from the link below:
Much of the notorious “Steele Dossier,” despite being paid for by the Clinton campaign, still “checks out” (New York Times) or has “proven to be accurate” (Washington Post).
The parts of the dossier the media are citing as true are merely echoes of their own reporting. Even a recent WaPo analysis of the 35-page document concedes that “many claims involve things that would have been publicly known at the time the report was drafted.”
Some press accounts have treated the dossier’s allegation that Russian officials offered Trump adviser Carter Page billions to end US sanctions as confirmed in September 2016 reporting by Yahoo News’ Michael Isikoff. But Isikoff’s “Western intelligence source” was almost surely the dossier itself. So the media used the dossier to corroborate the dossier. (Page, who has repeatedly denied under oath he met with the Russian officials cited in the dossier, is suing Yahoo News over the Isikoff story.)
What doesn’t check out at all, though, is the dossier’s most serious charge: that Trump officials secretly met with Kremlin officials overseas to hatch the hacking scheme against the Clinton campaign.
The idea that Trump lawyer Michael Cohen traveled to Prague in August 2016 to meet with “Kremlin representatives and associated operators/hackers” to discuss “how to process deniable cash payments to . . . anti-Clinton hackers paid by both Trump team and Kremlin” has been debunked. Cohen denied ever visiting Prague; his passport carries no stamps showing he left or entered the US at the time; Czech authorities found no evidence he visited Prague; and University of Southern California officials confirm he was on campus visiting his son during that time."
