Doubled gzip question

Under the “.htaccess” file on the server, I already have G-ZIP Compression setup as…

# BEGIN G-Zip Compression Exceptions
<IfModule mod_deflate.c>
AddOutPutFilterByType DEFLATE text/html text/plain text/xml
<IfModule mod_setenvif.c>
# Netscape 4.x has some problems...
BrowserMatch ^Mozilla/4 gzip-only-text/html
# Netscape 4.06-4.08 have some more problems
BrowserMatch ^Mozilla/4\.0[678] no-gzip
# MSIE masquerades as Netscape, but it is fine
# BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
# NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48
# the above regex won't work. You can use the following
# workaround to get the desired effect:
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
# Don't compress images
SetEnvIf Request_URI ^/files(.*) no-gzip dont-vary
SetEnvIf Request_URI ^/beta(.*) no-gzip dont-vary
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary

SetEnvIfNoCase Request_URI \.mp3$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \.mp4$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \.rm$ no-gzip dont-vary
</IfModule>
<IfModule mod_headers.c>
# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary
</IfModule>
</IfModule>
# End G-Zip Compression Exceptions

Under W3 Total Cache > Browser Cache, there is an option for “Enable HTTP (gzip) compression”. Enabling this seems to add it’s own G-Zip below it, which would double up?

Should I leave it disabled or modify the existing to work with it somehow?
