Frustration! Mulato or Español?

Just venting.

I found another entry of the marriage of Cristobal Manuel Castañeda Cobarrubias and Nicolasa Romero Godina. This one says Castañeda was a español. https://familysearch.org/pal:/MM9.3.1/TH-1-18453-8557-31?cc=1874591&wc=SS25-BZS:171936201,171936202,174796101

But the marriage dispensation I have says he's mulato. I downloaded a copy of the dispensation (I think their grandmothers were sisters), but I didn't copy the url! Where do I find this again?

BTW, I did come up with a bit of African DNA, so I figured his being a mulato must be true.

Thanks,
Laura
