Cloudfare SSL instead of Let’s Encrypt

I want to add Cloudfare SSL instead of Let’s Encrypt. I have add certificates from cloudfare to my website and the result showing like this.

… has SSL from CloudFlare, Inc…
Your SSL will expire in 5474 days.

But when I’m visiting to website or checking using ssl checker, it’s showing

The certificate will expire in 76 days.
Valid from December 7, 2022 to March 7, 2023

My question is how can I enable Cloudfare SSL to my website?

Try restart litespeed. I have had some problems for certificate take effect lately and litespeed restart had helped.

Tried. Not working.
