Had to ask about the bank since it wasnt stated in the original post. Sometimes the answer to problems can be simple -- Wasnt trying to offend
Are on blue and using custom UIs? If so you could try loading another UI to see if its just an interface display issue. If not, the outputfile command mentioned should help locate the problem
The outputfile command will create a text file of everything that character has that you can search through and see where the Lore item is located. Once you know where its at (what bag its in but cannot see/access it) then you can work on accessing it or just removing it

^ This is how I use it and the default location is your main EQ directory
