Pregmate HPTs

Has anyone used the Pregmate brand hpt? I feel like every single one looks like it has a shadow or indent. Additionally, each one has EVAPS. But the evaps are pink! Is this normal for an Evap to be pink? I know it’s invalid and out the window but it is frustrating. I tried a few tests to see if they all did that and they did.

First Picture from last night at 5 min mark (bottom test in time frame)

The top tests over a day ago (clear blue is evap) past the time frame by 2 hrs

But the bottom Pregmate test is at 5 min mark. But they all dry pink but it just seems like faulty tests. Any input is appreciated ☺️
