Anyone having issues with easy at home test results?

These tests are ridiculous. The first three tests are from last night, the second set are from fmu this morning, the last two are mid day today. The urine samples were the same for each test in their respective batch.

If this were chemical pregnancy, wouldn't the most recent two be negative like the middle batch? Also, look at the wild variation in the first batch. Seriously, what is the issue with this brand of tests? I've never had so much variation in any other pregnancy. Anyone have insight? Chemical? Evaps?
