Postive Cheapie but low CB digital?!?

I’ve been issuing digital a for awhile but this month decided to try some amazon cheapies. They had great reviews and we’re way way way cheapies so why not? Well the past 2 days I’ve been testing in the afternoon with the cheapies like the directions say and I have gotten a positive

but when I try to confirm with the digital it’s still saying low. I’m so confused? Had this happened to anyone else? I have used Afternoon and morning pee with the digital so I’m not sure what could be the problem.
