Ive started to look for the original documents for more details about my ancestors and occasionally can’t seem to original referencing document.

Ive started to look for the original documents for more details about my ancestors and occasionally can’t seem to original referencing document.

Example: for the record for “Antto. Blas Barbossa Lyez” https://familysearch.org/pal:/MM9.1.1/NBMD-54V (which I understand to be Antonio Blas Barbosa Lopez); I can’t find the (18 Sep 1712) baptism record under the images:
+ Mexico, Jalisco, Catholic…Church Records, 1590-1979,
+ Cocula, San Miguel
+ Baptisms 1711-1738
+ Page 54 of 738 seems to be from 21 August 1712 to 18 Sep 1712, and Page 55 starts with 18 Sep 1712, but I dont see the referencing record.

Am I looking at this wrong?
