module.ttf loading twice

Hi. I’ve been using Autoptimize for the last 3 years and been very happy with it.
I’ve been using it with “W3 Total cache”, “wp performance score booster” and “asset cleanup”.
Last week I tried to further optimise our website by setting a CDN with Stack Path (old MaxCDN)

Everything is smoother now but I’m having an issue with the modules.ttf which is now loading twice, from the CDN and from our server.

Path is: /wp-content/themes/Divi/core/admin/fonts/modules.ttf
And the referrer is: wp-content/cache/autoptimize/css/autoptimize_5e50f048897a5d981fb29b2e6d824b4b.css

FYI: The CDN is setup with W3 total Cache. I read somewhere that I must avoid setting the CDN twice in W3 Total Cache and Autoptimise because it could lead to writing issues. So I bypassed the CDN option in Autoptimise

Can you please help?

Thanks in advance
