[Bug]: Load DataObject doesn't respect Class when using SYSTEM Key

[cancan101]

Expected behavior

Objects are filtered to those with matching key and class

Actual behavior

Setting:

Loaded class (notice wrong type):

Steps to reproduce

Use DataObject with attribute set to SYSTEM Key.

Have two different classes with objects with the same key. Specify one of the classes in the loader. If that works, change the loader to the other class. In one case the wrong object will be loaded
