My Starpoints tracker (specifically just that) just switched from English to French. Language is set to English (although I'm accessing from Canada; US-based member). It has always been in English up until now.

This is on the main page and the My Account page. My Account page also has:

Everything else in English and fine.

*I did a search and used this thread...but is this a problem anyone else is seeing?
