cannot (re-) import technical service definition after changing parameter enumeration id

[ghost]

[Version] 16.1 GA3, 2016/08/23

[How to reproduce]

1. create technical service definition with an enumeration parameter (see attachment screen pic below to see the definition, for some reason it changes when I submit the bug and half of it is no longer visible)
2. as technical provider import service definitions
3. as supplier create marketable service, with a prices for enumeration parameter options
4. publish service and customer subscribes to service
5. terminate subscription
6. as supplier, deactivate service, delete service
7. change technical service "option-id1" to "option_id1"
8. as technical provider, re-import technical service

[Expected result] it is possible to import the technical service . Or if it is not possible (I cannot find a reason for this though), then the error message should be meaningful.

[Observed result] an error occurs at import time: The import failed due to errors in the XML file. Details: Exception thrown from bean. Refer to the Technology Provider's Guide for details on the XML file elements a technical service definition consists of. The problem here is definitely not an error in the xml file (see error log below).
