You're fine. That's just the way Conti does it. No worries. I'm not sure about the width labels (22 vs 1) but the diameter will be the same as your rims.

Also, you can stretch out tubulars on a clincher rim too - put it on there and press it up to 140 or so for a couple days and it'll be a lot easier to install when you're ready to glue it.
