Turns out Reagan Moss' new partner "Gal" is a typo for Slovakia's Jakub Galbavy, 17, whose only has 1 junior singles international (October 2021 Budapest Trophy) listed in his ISU bio:

According to this 7/31 tweet that includes a link to a Slovak federation document:
https://twitter.com/AnythingGOE/status/1686015386464952321
"Jakub Galbavy is released from the Slovakian federation at the request of USFS, he can compete from the 24/25 season."
I believe that there are supposed to be 3 Junior pairs scheduled to compete in the Nicks international - so of the 5 preliminary entries posted, they are: Enkina/Kovalenko (7th in their JGP Linz debut for ISR), Ashley Fletcher/Aaron Felberbaum (new this season, coached by Chris Knierim, and recently added to the ISP), and Saya Carpenter/Jon Maravilla (based at Detroit SC; ISU Junior age-eligible even though they are not listed publicly in the ISP right now).
The 2 Junior pairs scheduled to compete in the Middle Atlantics NQS are Sydney Cooke/Matthew Kennedy (new this season) and Moss/Gablavy.
