Many sources including the her own page made that mistake, Blaming TNA is only feeding a jerk off contest.
Chyna's page doesn't even list her age to begin with.
And because "other sources" also fail at doing research doesn't excuse TNA from it.
Whoever at the TNA warehouse and auto shop was in charge of putting that picture was too lazy to go on fucking wikipedia or IMDB and checking her date of birth, and whoever green lit it going on air (looking at you Gaburick) were equally as lazy. And this is just par the course of TNA being the baddest run wrestling company on the planet.
TNA is a company run by a bunch of literal idiots with little to no idea how to make people work for them outside of making nazis force them to (see how TNA handled their production staff threatening to walk after not being paid for almost 4 months). And now a company said nazis are involved with are in the process of purchasing TNA because Dixie was dumb enough to take out a loan with them using majority shares in the company as deposit, when there at the same time were multiple buyers willing to buy 50+% of the company off of her.
For the sake of the talent and ground floor staff, TNA needs to have every single person in a position of power backstage kicked out and some competent people instated instead. It's pretty obvious that since Pritchard (the only competent one backstage) left and Panda cut the funding in 2013 that it has been a slow slippery slope into death for TNA
