ADT2006: Sheet Numbers in Sheet Index generated via Sheet List Table incorrect

We're experiencing some technical difficulties using the Sheet Index. This is our first project, and includes over 50 files so far. See attached image.

I thought it had to do with some kind if illegal character (like a comma), but that doesn't seem to be the case.

Thanks,

craig,
just to clarify, are you using the 'insert sheet list table' from the right-click menu in the SSM? and, are the sheet numbers typed in or automatically generated?

Correct. The table is the automatic table you create through the SSM. All of the entries are fields and none have been edited.

It worked fine for the first 15 drawings or so. After we spent some time and created 50+ more drawings, we began seeing these problems.

I think it has to do with a renamed Layout tab in the sheet. The SSM has an "expected layout" tab that still shows the original name. So something there doesn't jive.

Other than that, we aren't experiencing any other issues using the SSM. FWIW this is our first project using ADT2006 and incorporating the vanilla AutoCAD SSM.

Anybody experienced this?
