Pregmate evap?

Are Pregmate known to dry like this? Not all of them did and the top test is water. My pee was definitely diluted when I did some of them. The line is so faint within the 5 min window but then sets dark. They are dry so I know this doesn’t count. I’ve had many losses and don’t consider it a positive unless it’s for sure and it’s within time frame. I’m just wondering everyone’s experience on Pregmate. Bottom pic is one test at the 5 min mark. I will be getting a frer later!
