Keith,Could we have some indication of whether the entire WG page has been lost in those missing cases, just the plain text version of the charter itself, or the charter milestones.The "Description" part of some WGs had gone missing during the transition for some reason. Here is the list of WGs that I knew had this problem: mext, 6man, ancp, bliss, hokey, keyprov, mediactrl, opsawg, p2psip, pcn, pmol, and vcarddav. There may have been more.
Add krb-wg to that list, also recently changed.
