Description
If the result of an operation performed in an evaluate/2 atom is a set, then the corresponding evaluated/4 atom only has a reference as a value and the items in the set are never given.
E.g.
evaluate(makeSet,(val(int,1),(val(int,2),()))).
has as output
evaluated(makeSet,(val(int,1),(val(int,2),())),set,ref(makeSet((val(int,1),(val(int,2),())))))
without the corresponding set_value/3 atoms that tell you which items are in the set

Research direction
Start by reproducing the evaluate/2 example in the issue and inspect how evaluated/4 output is produced for set results. Trace the related set_value/3 atoms; done means the evaluated/4 result is accompanied by atoms that expose every item in the set.
