Clear load line instead of pink?

J

Okay, so I’ve been using the pregmate testing strips. Every time I’ve used them, the entire strip loads across as pink and them adjusts in the time frame. The past two days, it almost looks like water going across and it leaves due runs? I’ve been using fmu every time, this is the first time this has happened. Thoughts? Why is it doing that? Is it invalid? Hmm
