Not sure they're the right ones as you did not specify, I fixed two issues with the listview's "Create" and the m2m widget's "Add":
* "Create" was eagerly evaluated, so it was translatable but it did not actually use the translation
* "Add" was not marked for translation at all, I marked it and exported it, it should be available soon-ish in rosetta
I've got no idea what you mean by "does not exist as upper case".
