Pepys diary grouping mislabeled?

If you go to this page and scroll down a long way (past a long section of The Diary of Samuel Pepys vol 1), you'll find a section labeled vol. 11 that actually contains Vol 10 Companion entries. (The vol 11 Index group that contains the vol 11 entries is further down.)

I don't know enough to fix this if it can/should be fixed.

>1 Cathery: The work ("section") itself is fine. Someone had set the canonical name of the Companion to "Index, vol. 11", that's why it had the wrong name on the Combine/Separation page. I removed the canonical name so now it's OK.

Thanks!
