I have taken a look at the issue you refer to in your Auctiva account and can see what you refer to. I do see the same thing on the Preview Page for eBay AU listings, and I have notified our engineers that this is occurring. I posted a test listing to eBay AU using the same information, and when it posted, the Restocking message did not appear on the listing, so I do not believe there will be any difficulty for you to post it.
If you do encounter a difficulty or have further questions about this, please feel free to file a support case from the Help tab of your Auctiva account so we can look into it further.
