Advanced Ovulation Test - Faulty Design?

I used the Advanced Ovulation Test kit last cycle and it appeared to work correctly, but I only used 6 of the 10 tests. So this next cycle I used the remaining 4 and opened a new box to use the additional tests to get me through the remainder of this cycle. Well, it's almost like it started over as soon as I used the new set! I used the new set today, and got a solid circle when the previous three days I had flashing smiley face! I took a regular (non-digital) ovulation test to check and it gave me a positive! So it seems like the test is rigged! You set it where people get a solid circle no matter what on the first day... even if it could have been the day they ovulated. If the Clear Blue advanced ovulation test is really accurate, why would you need to rig it to give certain results? I'm very disappointed as it's just made me more confused about this whole process! It seems like the only reading that could be accurate would be solid smiley face, so on day one, you would always get a solid circle and then all the other days would be a flashing smiley, when in reality it's just a program waiting for the actual ovulation day. Makes me feel like I paid extra for something that is only tricking me to believe that I have a good chance of getting pregnant! I would not recommend this product now that I know how it really works! Is my assessment accurate?
