I'm exporting a space to HTML and I want to insert some specific stuff into each page generated.
So I edited both Export Layouts of the space (Browse Space > Space Admin > Layout).
But when I export the space, my changed aren't used, all pages are generated with the Default Layouts.

So, I tried and changed the Export Layouts on Site level (Dashboard > Administration > Look and Feel > Edit Site Layouts).
And now it works!

But why doesn't it work for the individual space.
I want to edit the export layout for each of my spaces to be different.

Another user was able to reproduce the failure.
