I have two forums with the same name - General Discussion- in different categories. When I delete a thread from the General Discussion forum under the 'Moderators' category I set up, the page jumps to the General Discussion forum under the category 'Discussion Board'. In terms of the web address, I go from 

community/general-discussion/

to

community/main-forum/

The latter was originally called 'main forum' but I relabeled it to 'General Discussion' but see it hasn't changed the web address. I'm just not sure why one would jump to the other unless it is somehow referencing the name??
