Comment (by karsten):

 Good catch.  But it's not a bug.  Here's why:

 Your relay writes its full IPv4 exit policy to its server descriptor, but
 it only includes a summary of its IPv6 exit policy in the same document.
 The reason is that normal clients don't care about the details anymore but
 only use the summary these days.  If an exit node rejects a connection
 they thought was permitted, they'll try somewhere else.  In theory, relays
 could switch to only including an IPv4 exit policy summary in their server
 descriptors, but nobody wrote that code yet.  In this case it seems like
 both summaries are the same, even if the detailed exit policies differ.

 So, there's no way how Atlas could display the long form of your IPv6 exit
 policy.  But can you think of a way to make this more intuitive for Atlas
 users?  Should we throw out the full exit policy entirely?
