2 Sparse Bundles?

I am looking at my Time-Capsule and I am seeing 2 different Sparse Bundles. "Name.sparsebundle" and "Name 1.sparsebundle"

The former is created about a week prior to the later, and only has 137 GB.

I'm trying to go by memory here, and IIRC, by default TM used to create 2 different bundles, is that correct? Just in case I am remembering wrong, I am checking here as I'd like to clear out some more room on my 2 TB capsule, but I do not want to risk destroying everything if both are needed.
