CB adv digital opk stuck on solid smiley face?!?!

Maria
Someone told me a while ago when u get a solid smiley face, it stays I. The display screen for 48hrs. I'm like, ok, ur test is broke. ( didn't really say that tho). We'll I got a solid face yesterday afternoon and I went to test this morning, AND ITS STILL THERE!! Wtf?!! Soooo I opened a new box and used the new handle part and got an O but I got a smirky face on my regular CB opk. I also heard u ALWAYS get an O the first test we the advanced ones. Is this right??? My temp didn't dip yet and I had 2 other positive opk so I don't think I o yet, but idk why the advanced on says O.
