is racial miscategorization on old catholic church records common?

I'm asking since when I will looking up birth records, and marriage records from my 5th great grandfather silvestre villaneda, and some of his siblings, the records were inconsitiant of the race part. for example silvestre's marriage record says he's espanol, but his birth record says he's indio. one of his brothers ygnio/hignio birth records labels him as coyote. two of his siblings clemente, and maria antonia are also labeled indio. his sister reufgio is labeled as espanol.

I am soo confused.

have any of you guys have this problem?
