Clearblue Ovulation sticks

Hi all so I tested yesterday and got a solid smiley face, I thought that the smiley remains on the tester for 2 days, but mine did not. I tested again this morning and got another smiley face which after a couple minutes disappeared. Not sure if the test is faulty and also how should I read it as peak or high?

Please note this is a solid smiley face and not a flashing one.
