OpK - Clearblue digital advanced - incorrect result?

Sw
Hi Ladies
Hoping someone can give me some tips if I have a faulty device. It's the clearblue digital - dual hormone...
Currently my device gave me a Peak result however I can't retest as it won't let me, as you know.
But when I look at the stick I see it blurred ... See pic
 Do you think it's incorrect result as I am not sure ....any ideas ?
