Correct that Kerr was the 25th SOTH and it was PRESIDING over the 44th Congress. Same page shows Johnson as our 56th SOTH over the 118th Congress. I think Scalise's slip still stands, and is likely intentional based on the reaction of the people behind him, including Mike, but you are correct.
Fyi, Kerr was not 44th SOTH, it was the 44th Congress, per Congress's own website. https://history.house.gov/People/Office/Speakers_Numerical_Order/
