7.x Transformation create 3.x InfoSource, Update Rule and 3.x DataSource in BW mySelf - Why?

Hi Friends!

Strange situation here. In our BW 7.5 system, when we activate or import 7.x Transformations, it creates 3.x InfoSource, Update Rule and 3.x DataSource in BW mySelf`. These 3.x objects are not needed; we are able to load data through 7.x Transformations using DTPs after deleting them.

What causes this behavior?

More importantly, how can we suppress or prevent this behavior?Strange situation here.
