Etsy Did Something Funny

I was just poking around The Scented Djinn Etsy site, cleaning things up, updating stuff, and finally adding a credit card payment function, when I noticed that all my products were listed in CAD -- Canadian currency. So, without freaking out (too much) I did a little research and found out that sometimes when the credit card function is chosen, it temporarily changes the currency. I went into payments and currency and it was all in USD, so I saved it (again), then checked the site and it's back to USD. Very odd. I suppose I should watch these things in the future, yes?
