Building with Dist option doesn't include themes?

Hello.

I am using Pinguy builder on Linux Mint17.3.
I put some themes and icons to make Mint look better for me.

when I create the ISO with the Backup action it work fine, but when I create the ISO with the Dist the action, the default look of Linux Mint shows up, so it did not remember my setting for the Icons and themes.

Any help will be most appreciated.
