What do you think?

Posted this in wrong section previously so here goes. POS. Thought something looked a little darker but Signif was in a hurry to get to Walmart. So put it away. Two hours later found this. It’s still wet so not Evap.

What do you guys think?!CD21. It’s got color to it!!!

UPDATE: CD 23 today. I kept retesting. I kept getting these double lines with various brands but post the time frame to test. Then they begun to appear fainter and fainter as I tested. Then none at all. I’m kinda devastated.
