Export CSV in Shipping Rates doesn't work

Question

I have Magento 2.1.1 in production mode. I go to:

Stores -> Configuration -> Sales -> Shipping Methods.

When I try to export the CSV example to upload the rathes, the system after 10 seconds redirect me to the home.

I tried to debug the problem but it's not any error apparently.

Thanks for help

The Magento 2 sample package was not installed.
