Element Based Edge deletion costum viewpoint

Hi all,

i created a custom viewpoint in capella studio and defined a diagram description with sirius in a odesign file.
I exported the viewpoint and installed the viewpoint in another capella studio instance and everything works fine.
But when i install the viewpoint in a capella (not capella studio) instance the “Delete Element” edition i defined is not working. Is capella not able to interprete the expression? And which software do i need to install to upgrade capella so that it is able to interprete the expression? In Capella Studio everything works fine. I would appreciate if anyone can help me with this issue.
