I can't find a source to confirm the clef used by the Heckelphone, but the treble clef would make sense since it is "similar to the oboe but pitched an octave lower" and oboes use the treble clef. If true, that would indeed mean the treble-8 clef should be used in concert pitch mode.

confirmed in latest master, will work on a fix
PR made with fix, see https://github.com/musescore/MuseScore/pull/3824, awaiting review and merge.
For future reference, it's a good idea to include sources when reporting issues with instruments. Wikipedia is an acceptable source.

The table in the this book's preliminary does confirm this.

@quaver crafter Great catches!
The link to Forsyth (REALLY great resource, BTW) was not working for me. Here is an alternative link - https://www.scribd.com/document/298140213/Forsyth-Orchestration1914
If we've got the Heckelphone, we might as well add the Heckel-clarina. :-)
Heckel-clarina was probably the only thing Heckel ever made that wasn't absolutely amazing.
