Magento 2.2.2 can't import costumers, "Please enter a correct entity model."
When I try to import a "Customers Main File" and click on "Check Data" I get the following error:
"Please enter a correct entity model."
It also does this when I try to import "Customers and Addresses (single file)".
"Products", "Advanced Pricing" and "Customer Addresses" work just fine.
It's not not in the csv because I also tried it with the magento example csv and it gave the same error. I also tried searching for logs but I couldn't find anything, but I might have missed something.
