In some rare occasions, data stream content can get mislabeled and displayed in another data streamID.
Example:
Datastream Alpha with content A, B, C.
Datastream Beta with content X, Y, Z.
When the issue occurs, content X, Y, Z becomes labeled as being part of the Alpha datastream, and vice versa, which can then display on the wrong stream.
To reset the data to its proper labeling and stream, a restart of the game job may be required.
