Problem might be with name of map itself. Map name is "QA_DVD", but that "_" separator might be taken as end of name, which means that offsetfix/ADT adder/whatever else can take "DVD" as X position of ADT, instead of number which comes after it, that can lead to a lot of problems if some of applications you use don't count with such names (Client and Noggit don't have such fails in code, but for instance ADT Adder does).
In general I don't recommend working with maps which have "_" in name. Rename that map in map.dbc (and folder and ADT files too) or use another map (for instance use some of PvPZones/Transports or create new map).
