Connecting objects for further use within a type choice fails

Affected Version

Xyna Zeta: 0.7.9.5

Xyna Factory Server: 8.2.11.18
Process Modeller: 1.1.19.4

Problem

Further use of objects used for a Type Choice is not possible.
For example:

Using "Auftrag" as Input for a mapping within the type choice is not possible, because the connection between the objects cannot be established.

Looking into the client information shows that the ambiguity solution will be sent to the backend but the response does not show the resolution of the ambiguity. The ambiguity still persists.
