On version 1.11.2 When a relay has group assigned in the logic assignment section and you reopen the unit and click the logic tab and you will see the ticks in the allocation boxes but the logic groups which has a group assigned are blank. When you click on the drop down box to open selection groups the group that has been assigned will be highlighted, release the box and the group will be displayed. The unit is still internally programmed when the display is blank. Version 1.11.1 works fine.
