Not sure about the errors you are all having as I've not tried to list or relist anything since ebay has posted other system issues. Here is what they last posted:
"Some listings that completed this morning were not being correctly displayed in the Items I've Won or Sold Items sections of My eBay. These were also not being reflected within the seller's Account Status section. ......"
While they are also stating it was corrected and that they are now working through effected listings, I don't think it truly has been corrected. I contacted Live chat help this morning and they said it should be done by tomorrow (Monday).
So, I'm wondering if all these errors you have compiled here are a related matter.
You may want to try live help or sending an email.
