Bug: Invalid bookmark link on cache page

[+MartyBartfast 313]

When looking at this cache page https://coord.info/GC2G6DX

the My Bookmark Lists box says it's on list "DT Grid 7", clicking the link for that list takes me to this URL:
 
https://www.geocaching.com/bookmarks/view.aspx?guid=8dfe2e81-c3fb-4de3-a850-37beb5b124f7

 

That page states:
"The bookmark list you are trying to view has been deleted."

"DT Grid 7" is a list that I created some time ago, but I deleted and re-created it. The correct URL for this list is now:
https://www.geocaching.com/bookmarks/view.aspx?guid=14ea1858-9005-4af9-88c4-523cb77e3c32

Shouldn't all links to the original, obsolete, list have been automatically removed from cache pages? As things stand there is no way I can remove that cache from the obsolete list.

 

FWIW I believe there may be other caches with links to this same list, but I can't verify that for certain.
