Symptom
The pop-up showing "Unsaved changes There exists a non-saved draft for this model (Last edited on XXXXXXXX). Would you like to import this draft?" keeps showing up when opening a diagram in Process Manager Editor. Other users are unable to see the pop-up.
Resolution
The user may have updated the diagram long enough for the draft to be created. After that, the system keeps asking the user what to do with the draft and user did not reject the draft which did not create a new revision of the model. Other users are unable to see the draft pop-up because it's not their draft.
When a model is opened in Editor, and it's changed (but not saved), Editor regularly sends the changed model to a server, so that if the user made some changes and forgot to save it, it's not lost.
This draft is shown only to the user who has been working with it.
To get rid of the message, the user should either "Reject the draft", or create a new revision, so that it's clear that this user has saved more recent changes.
