Flex Builder Question - Not seeing files during AIR export

I've got a weird Flex Builder question I hope my readers can help me with. I'm working with an open source Flex project (ShareFire) and need to build the code myself. I created a new project in FB and then manually copied the files over from ShareFire's SVN drop.

When I did a debug build, I noticed that the non-code files (one SQL xml file and a CSS file) were not copied to bin-debug. Not thinking much of it, I just copied the files manually to bin-debug.

But this wasn't a real solution and it's now biting me on the rear. When I go to export a release build, the AIR File Contents screen refuses to list the other files:

I thought perhaps I had messed something up by manually dragging files into the project, yet when I made a new file from within FB (readme.txt), it wasn't noticed either.

I write these posts for free — if they're useful to you, you can buy me a coffee. It helps more than you'd think.

Any ideas folks?

p.s. Sorry for the lack of posts this week. Been fighting the flu the last few days and the flu is winning.
