how to fix this error on Dokan: "You can not add more than one vendors product in the cart"

Question

I get the error on Dokan multistore and I already check on /general setting and selected multiple category and disable single seller mode but nothing works. Im really tired, I checked on internet and youtube and I do not find the problem.

I expect help from those who already have the problm and fix it.
