First Response OVULATION tests

Kristin • TTC - mama to one lovely LO - RPL
Anyone have odd or confusing results with these ovulation tests? I used two boxes of them, and they were all negative, even when both clear blues and Internet cheapies – four different kinds total – were positive. The others Grand chrome high sensitivity – so I know it isn't simply  that. Then today, when all the others are negative, all symptoms and apps say I've already ovulated, this one – last in the second box is blaring the positive. Any thoughts or advice?????
