ok… NOW this is weird… my guess is probably mistyped sticker or something.
right now the newest batch is 8.
I am not sure how can you get 2.
As far as i know this batches should not bother you.
The version number is important
That indicates the pheromone formula.
If they change some of the molecules they will change the version number.
batches are just batches with little modification to the scent.
If you haven’t read it already my opinion on the batches you can see it here
