Oh... it usually doesn't do that.
There is a bit of a problem with the editing of the name though, you probably did that along the way:
If you rename the node and keep the "- version XX" in, it'll get added to the table name.
I'll fix that obviously, probably will have time for that on the weekend; until then, you can just change it back by removing the "-version" part when renaming; then it shouldn't get extracted with it anymore, and it won't get saved into the pack file either.
