Back in 04 - 07 or something around that , Zhong Cha brand was available for franchise kinda style with difference that there was no material check.
Means you could purchase a 1000 wrapers with that design and press , pack into it whatever you want. So on market could be 2 identical wrappers but with completly different material inside from two different producers. Therefore there is no fake or real.
I think from around 2010 the company COFCO bought the Zhong Cha and since then their products are protected by law in matter of faking. Anything before that is just whatever , could be Zhong Cha but also can be Mr.Ling, Mr.Wang ...or whoever had money and felt like investing into the puerh tea covered by known brand. Not mentionig the fact that actual faking this brand is continuing till present.
That's why they call it generic cake.
The misprints were and are common till now even on offical level ( on traffic signs on highway or in city ) , let alone some private tea company.
Packing can be done in any style right now. Yes, the new syle of packing outrules the possibility of tea being old , but old style one could be done a month ago.
In fact, I was packing it sort of same way before I learned how to make the proper star with tile and the back
For some guidence of authencity of the nei piao or wrappers , there are some books
https://www.pageoftea.com/fake-puer like here, but again. If you are making an old puerh, the missprinting is not a big hassle. Let alone , you can use the original wrapper of sold / drunk tea , to wrap your fake cake into it ( of course this is not done on big scale and probably not on some cheap cakes which appear to the western buyer on internet ) .
Long story short, if you are not serious collector , don't bother with autheticity too much. Focus on $=what you want to have in your cup. I met many people who drink horrible tea but convinced them selves they like it because they were told it's very old and valuable piece they have. Life is too short to prioritaze ego above the actual joy
