8:18 PM PT -- A rep for Target tells TMZ ... "We will no longer be selling this product in stores or online. We’ve also ensured the product's publisher is aware of the errors."

Target's under fire for selling Black History Month material in their stores with factually incorrect info -- namely, grossly mislabeling historic Black Americans.

The ill-timed snafu was pointed out by TikToker @Issatete -- who posted a now-viral video of what she says she found in a Target near her. In the clip, she shows off a magnet-style learning activity book called "Civil Rights."

It comes from a children's product retailer called Bendon -- but this user is mad at Target for hawking these books, which she says have names of prominent Black figures mismatched to their photos.

Take a look ... you'll see what she's talking about. There are at least 3 examples of completely mislabeled names, and Issa is pissed, calling it more than just an oversight.

The user, who apparently teaches U.S. history, gave a rundown of the mistakes she immediately noticed -- for instance, the picture of Carter G. Woodson in this magnet-book is actually Pan-Africanist civil rights activist W.E.B. Du Bois.

Elsewhere in the book, the picture labeled with Du Bois' name is actually educator and author Booker T. Washington -- while Booker's snap is actually Woodson. Talk about a mess!

Issa says action needs to be taken immediately ... writing in the caption that mistakes happen, but it only takes one person to point it out and ask for corrections. Now that she has, she's calling on Target to remove this product from its inventory.

The outrage continues in Issa's comments as many people are asking why no one bothered to proofread the book at least once.

The publisher's yet to respond to the viral post, and although some are going so far as to claim the errors were deliberate ... we gotta say that seems unlikely, because an intentional mislabeling like this is too outrageous to comprehend.

Whatever happened, the timing couldn't be worse ... on this eve of Black History Month. Rough start for Target and the book's publisher, for sure.

We've reached out to Target and Bendon for comment ... so far, no word back.
