ClearBlue OPK Error

Dara • Director of Innovation, married June 2014, 2 great stepsons and pregnant with a baby boy due 3/28/16!
Has anyone had issues with the ClearBlue Digital opk getting stuck on the results reading post usage? I have had three in a row get stuck on the peak smiley face after ejecting the stick. They have then been frozen and have not worked again.
