Specify a cache validator only works on developer mode (mark woff fonts)

When I test gtmetrix, mark me specify cache validator four lines:
fonts woff. (4 lines calling)

This specify cache validator rule is well placed on my server in the file htacces! if I put Cloudflare in development mode I do not get the error but when I remove development mode it comes back out, I have reviewed htacces and everything is correct.
Is there any way to tell Cloudflare that specify cache validator are set correct?

many thanks!

finally this been done alone waiting all day now is ok
