Content from uninstalled ep is in game

[ethyrdude]

Not sure exactly how this happened but I have a flavor book from EP 11 (Into the Future) that I keep seeing in game but I don't own this EP.  Not sure if it's causing a problem as my sims seem to read it all the time without an issue but it could account for mysterious crashes so I would like to remove it.  The problem is where would this item be located?

The name that comes up when my sim reads it is - Gameplay/Excel/Books/BookGeneral:EP11FlavorBook3
