"No resources match the configuration" when selecting different layouts

"No resources match the configuration" when selecting different layouts

I'm currently working on a tablet layout for my app, and up until now
everything has been working fine. However, when I load up my layout now,
and select a tablet-sized configuration from the drop-down list (Nexus 10
or 10.1 WXGA), I'm met with the following error:
No resources match the configuration
, , Locale Language ___Region __, , sw800dp, w1280dp, h800dp, Extra
Large Screen, Short screen aspect ratio, Landscape Orientation,
Normal, Day time, X-High Density, Finger-based touchscreen, Soft
keyboard, No keyboard, Hidden navigation, No navigation, Screen
resolution 2560x1600, API Level 17
Change the configuration or create:
res/layout-sw800dp-w1280dp-h800dp-xlarge-notlong-land-notnight-xhdpi-finger-keyssoft-nokeys-navhidden-nonav-2560x1600-v17/newtabletlayout.xml
This is surely some form of error, as I'm using nothing but the standard
Nexus 10 configuration, any ideas why it won't display?
