Property invisible

Hey,

I used to have 4 properties (1 solid, 2 shell, 1 beam) in my model. My problem is, since shortly HM does not display them anymore. I can still see the beam property in the model explorer, but none of the other 3. Strange thing is, when I exported the solver deck, the properties have been written correctly to the keyword-file. As I tried to create the missing ones again, HM promted that properties with this name already exist. Has anyone else experienced this bug?

Best Regards

Gottfried
