Taz-Mania Misprint?

[Sinistral]

I'm just playing a few games this afternoon when I noticed the back of Taz-mania seems to have a sticker which says "rounds 5". You can see through the sticker though as it's slightly transparent and you can see "rounds 6".

Now, I've not played Tazmania much, but my question is how many rounds are there really? and is everyone else's copy the same?

I've just checked SMS power and they have 2 scans, one with a sticker like mine and another without which says 6 rounds.

There's five rounds, some inserts have the sticker on, some don't

I have both in my collection.
