Clearblue Advanced -HELP!!

So I’ve been using the one on the right since my ovulation window started and I’ve been having flashing smileys - this morning I couldn’t find the test device so I used a new one that I had (left) and it showed the circle which means “low” - I found the one I had been using and tested them together in a panic, the new one still says circle and the old one continues to flash smileys which contradict each other. Today, according to the calendar, is ovulation day but so far all I had was flashing smileys and now this circle, no peak - this is weird? I thought it checks for the elevated hormone? Why would one test say I am “high” and another say “low”? I have also been checking CM and bbt just to make sure. I don’t know what to make of this testing device though. Can anyone help?
