Clear blue advanced digital

I got my static smiley on clear blue advanced digital on cycle day 14 after 9 days of flashing smileys. I was also using ovulation test strips to see if I was actually having a surge and was still getting high readings a couple days after static smiley. So I had another new clear blue advanced digital test I decided to open and use also to make sure I wasn't still ovulating and I got a flashing smiley yesterday cycle day 17 and a static smiley cycle day 18 today so I'm confused and I'm not sure which peak I should go by. The first picture is cycle day 14 when I got my static smiley and the second picture is today when I got my second static smiley.
