Clear Blue Advanced Digital Ovulation Test- two holders, two different results???

Hi there! I’m am so confused and am begging for some insight on this. From March 14th, 2025 - March 25th, 2025 I have had 12 high fertility days, with no peak day. I can’t find anyone else online that has had that many high fertility readings. I got suspicious and went and bought a brand new Clear Blue Advanced Digital Ovulation Test. The next morning, I used both the old and new holder to test my urine. The old holder showed high fertility AGAIN for the 13th day in a row, while the new holder showed low fertility. Which holder do I believe and why do I have so many high fertility days but no peak days??? To add: I have been recently tested for PCOS and endometriosis, both test have come back negative. I even had an ultra sound down and nothing was found. I am also not on any birth control.
