Pregmate indents??

What is up with my pregmate tests?? I ordered two bags. The tests in the bag I used first NEVER got an indent or false positive. I started using the second bag yesterday and noticed right away the tests in general were a little different, and I did use evening urine but I got the worst most obvious colorless indent. So I tested two more times to make sure it wasn’t a bad test. All tests had the same indent. So I tested it in water. Same indent. I took a FRER, negative.

This morning I tested with FMU and I can’t tell if I see some color or if it’s the stupid indent! My cycle is messed up so my period is technically due end of week but it could be a week later due to being irregular.

These are last nights:

This morning(both pics are of same test):
