Baptismal certificates in Aguascalientes 1807-1812

I have not had success in finding baptism certificates in El Sagrario for the years 1807-1812. When I do a general search in FamilySearch, I find 2 children listed for Pablo Hernandes and Cerbula Canedo, which indicates to me that certificates exist. But when I look in this link I cannot find the certificates.

This is the period when certificates were in different books depending on whether you were "espanol" or "indio". I believe that the certificates would be found in the "castas" book, because all other certificates for this family were indio.

The 2 specific certificates I am looking for are for Jose Susano Hernandes, baptized 3 June 1808 and Maria Yrinea Hernandes, baptized 18 April 1810. The link that took me to this information was:

The certificates for this time period are very difficult to read because of the handwriting, but I have looked and looked. Maybe I am just missing them, but I am frustrated. Any help or suggestions will be greatly appreciated.
