Invalid shortcut shown for direct dialing or contacts

I have a Samsung Flip 3 with actual OS and KLWP pro with actual version.
I use my theme since years and have shortcuts for direct dialing which work till now without problems.
Yet I wanted to create a new shortcut for a new contact for direct dialing but can not. Always I get “invalid shortcut” -when I try direct dialing the same as open contact. This for the new contact the same as if I choose a contact that still works with direct dialing.
My contacts are since ever by my exchange account synchronizing to my Samsung. These contacts working till now. But if I try the same again, I get the message invalid contact. For me it seems there must be a change in KLWP reading contact.
