Missing Tlaltenango matrimonio civil records: 1913-1914

Hey everyone --

I was looking at the Matrimonio Civil records for Tlaltenango, and it appears the records for July 1913 to July 1914 are missing, from the 1913-1914 file.

Here's the link:
Mexico, Zacatecas, Civil Registration, 1860-2000, Tlaltenango de Sánchez Román -- Matrimonios 1913-1914

I was wandering if anyone knew if these files (July 1913 to July 1914) can be found someplace else. Thanks in advance for any help!
