Nightwing ground slam meter burn


I have an unpatched version of injustice (no xboxlive account)
The db2 mb (ground slam) in staff mode sends my opponent floating up and away from, rather than floating up and towards me like in the combo videos I have been watching.
Might this have to do with my version? It being unpatched? Or am I doing something wrong? Any help would be appreciated!


So they bounce up normally but then kinda float away from you? has to be because it’s the unpatched version
