Woocommerce stock manager doesn´t work

Hi.
In the backend view of the plugin, I cannot see the following columns of information: manage stock, stock status, pending orders and stock. This is what I can see in the woocommerce action manager backend: https://accedecliente.com/descarga.png

I tried it on two different websites, deactivated the other plugins, etc … but nothing.

What is the problem?

Thank you.
