I can confirm that the English version is correct, so it seems like it's only the Finnish version that is incorrect.
But are you really unable to see how the set looks like in the Finnish version without someone posting a video of it? Or are you thinking that the issue is bigger than it actually is? I mean to my understanding it's only one number in the name of the set in the Finnish version (it is supposed to say 2 instead of 4) that is incorrect and everything else is correct, so you shouldn't need a video of the entire process of completing the set and opening the pack. 2x 83+ is the correct pack. You only need to check the name (and possibly the description) of the set in the Finnish version.
And by the way, do you happen to know the reasoning behind the 5 collectible pack being 2x 83+ instead of 3x 83+ or even 4x 83+? I mean as OP said, with 10 collectibles you can get a 4x 84+ pack, so it's a bit strange that 4 83+ overall player items cost the same number of collectibles as 4 84+ overall collectibles?
