Difference result from two holders, why?

I have two Cearblue advanced ovulation packs, one is from US, another one is from UK, today I use two holders and two test sticks to test in same time and same urine, but I have two difference test results, one holder shows Low Fertility, and another one shows Peak Fertility, can you let me know what's happen now? thank you.

Our tests are sensitive to 40mIU/ml LH and should show a Surge/Peak at this level and above.  They can both also show a Surge at levels as low as 22mIU/ml LH and this will depend on batch variation and the previous tests done in that cycle. 

Results like yours are therefore to be expected if the level of LH in the sample tested is between 22 and 40mIU/ml and this can be normal at the start of the Surge.  You have found the information you were looking for so stop testing for this cycle as today and tomorrow are your two most fertile days.
