EBay allows to create "space characters" only watchlists. The problem is that you cannot select and delete it.
I accidentally deleted the images.
Press "Add to a new list" and give a space character
The space characters listed here but cannot be selected
I tried to create a custom list that had only spaces in the name but received an error message when going through the Watch List page.
However, I was able to create a space-character named list from an item listing by adding to a new list as you described.
In any event, you should still be able to select one of those lists from your Watch List page.
Click on the large "Watchlist" heading to reveal a drop-down menu of possible lists, and select one using the up or down arrow keys to highlight the empty name, and then use the enter key to load that list.
Once you have loaded the list you should be able to delete it using the delete button in the upper right corner of the list page.
