Yes, this is expected behavior. Looking at the role definitions, the application roles are intentionally set up that way, and the system would basically break without them. It is a mistake that we are hardcoding the organizational roles, so you’ll have to find some workaround.
I assume you’re talking about something like openmrs_drug_1.10.0_20141226.sql in the CIEL dropbox folder? See Andy’s comments here. More or less, yes they are free to use, but probably not available in French. If you translate to French, I assume Andy would love to get your translations. You should ask him this question in the Terminology category.
