Update!
I finally had the chance to call Taylor Technologies about the problem I was having. I gave them the lot number for my R-0871 (Lot B1067), and they informed me they had received a few calls about this specific lot number. They are sending me a replacement bottle of reagent, and they want me to ship the old bottle back to them for further testing.
So it looks like it was just a bad bottle of reagent. Will report back when I get the new bottle in and can confirm the test is working.
