I did not find out if this is a problem in the XML data from the Wiki or in the parser.

Why do I still see the message?

[GerdP]

It seems the file was cached by CachedFile. I did not find a normal way to clear the content.

Replying to GerdP:

I did not find a normal way to clear the content.

Pressing the blue reload button in the imagery preferences should do it.
