VMBLCDWB Sunrise/Sunset Problem

I have just installed the VMBLCDWB pushbutton & timer panel. I am trying to use the sunrise/sunset program step, but can’t get it to work.

I am using the latest build of VelbusLink V8.10.0.2597
I have enabled sunrise/sunset related program steps.
I have selected relevent program.
Sunrise and sunset are enabled.

I am using timed periods also within the program step, which is working fine, just no sunrise/sunset.

Any ideas would be very much appreciated.

Should work fine. If not, hereby some things you can check:

The option sunrise/sunset related programs must be enabled.
The program group must be selected trough ‘operate’.
The buttons must not be disabled or locked.
The program must not be disabled for those buttons.
