Error while Vote in Express ECO

I faced two problems in Express ECO:

1. I have part which is in Released state, I added that part to Express ECO and change the "Item action" to "Revise", but while "Approve Plan" vote, I got error something like this:

Internal Error: failed to get the transition to promote the Part from Released to In Change. what does it means? I am learning change management, specially express ECO and DCO, so what are the steps do I need to follow? I watched demo videos on aras website, follow what they did, but got above Error. and 2. While creating a Express ECO, When I try to add the which is in "Inwork" state, Then also I got a error that Part should be in Released or Preliminary state.
