5.6.0.7 New blank / edit RDP host session error

Hi

After upgrading form 5.6.0.6 to 5.6.0.7 when I try to edit RDP host session or add new blank session I've got this error

ArgumentOutOfRangeException - InvalidArgument=Wartość '4' nie jest prawidłową wartością dla 'SelectedIndex'.
Nazwa parametru: SelectedIndex

Translated from polish means: '4' is not a valid value for 'SelectedIndex'
