WP Hummingbird - gzip error

Hello. I'm having trouble using GZIP COMPRESSION in the plugin WP Hummingbird. My apache server is enabled gzip and NGINX. You can check it at: http://checkgzipcompression.com/?url=https%3A%2F%2Fmtpro.co

I have deactivated all plugins and is not incompatible with others.

Please help me solve this.
