I am creating a CMMN model. Each time I create a Case File Model, it appears twice in the Model Explorer tree. Once just as a ‘Case Plan Model’ sub-tree and then again as a ‘Case’. The sub-elements are thus shown twice. If I try to delete one of these trees, the other tree also is deleted.
I have attached an image that shows the inconsistency with two trees duplicated, expanded. This is a very simple example with only three elements!
How can I clean this up so there is a single representation?
