The "drift " is a known issue from neptune. There is a user on here @Brasileiro561 who made some needle holders to put on the caps to hold the needles vertical. This helps eliminate the drift in results.
I do not think this is a correct recommendation. If he installed the reagent a week ago, it is totally unrelated to the needles sucking air due to being slightly crooked. The bottles are full. The printed solution would only apply to users who are having it happen in the last week or two.
