Initiator still “Other”

Hi sir,
I just implemented this ( https://support.cloudflare.com/hc/en-us/articles/115002816808-How-do-I-enable-HTTP-2-Server-Push-in-WordPress ) but still the initiator still “Other”.

Can you guide me on how it works also it’s duplicating my resources to load like the preload js/css and the autoptimize js/css.

Thanks in advance.
