Button labels showing as Skuid.save or skuid.cancel in lightning components

We have a Skuid page where we are using the save/cancel buttons on a table. If you view the skuid page in preview mode the button labels show correctly as save or cancel. However when you view the skuid page within a lightning component the buttons incorrectly show [skuid.save] or [skuid.cancel]. Does anyone know why this might be occuring?
