Investigate and resolve discrete session "errors" when loading and SMTK file.
Errors like the following appear when loading discrete sessions:
ERROR: Entity 296e338f-a165-4636-9d6a-a5dd6371d060 invalid id 296e338f-a165-4636-9d6a-a5dd6371d060 has no matching CMB model item
INFO: Unknown entity type 0 being transcribed.
ERROR: Entity 185e2c04-c9c2-498b-a778-0c766f91d669 invalid id 185e2c04-c9c2-498b-a778-0c766f91d669 has no matching CMB model item
INFO: Unknown entity type 0 being transcribed.
INFO: Model - Read: operation succeeded
INFO: Model - Load File: operation succeeded
These should be removed unless they are actually errors (which they do not appear to be since the model is loaded properly).
