[Pier] Problems writing PierSeaside to GitHub

Hi All - Lately I've updated the table-of-contents link in Pier to visit its parent, not the page being renderered, and it's resolved one issue, but writing the code to GitHub has been challenging.

The class PRTocRenderer is in Pier-Seaside-Visitors, however what is listed in Iceberg is pier-seaside (lowercase and missing visitors). When committing changes, it doesn't to leave Iceberg. The steps and pictures are at:

Is this problem caused by the package name being lowercase, or that it is missing the suffix? Any suggestions on how to fix this?

Thanks,

John
