htaccess not working?

The AIOSEO htaccess editor is quite a bit different than my actual htaccess file. I added a cache control header code in my file editor like so:

<filesMatch “.(ico|pdf|flv|jpg|jpeg|png|gif|svg|js|css|swf)$”>
Header set Cache-Control “max-age=84600, public”
</filesMatch>

What AIOSEO shows in the editor is this:

# BEGIN CACHE CONTROL HEADERS #

Header set Cache-Control “max-age=84600, public”

# END CACHE CONTROL HEADERS #

If I try to use the code that is in my file editor directly in AIOSEO htaccess editor, my website will crash. Only way to edit my htaccess file is through my file editor. I can not use the AIOSEO editor. If I copied and pasted my real htacess file with the one that is shown in the AIOSEO editor….they are completely different. Its as if the AIOSEO just shows a sanitized version of it which can not be altered….or else a website crash I will get.

Any input?
