Illuminated only start and end?

[KabirRaut]

Moinsen,
I have received my new PL4 and would like to program it. The lighting courses 1 to 3 go as intended with time and brightness. From lighting 3 I cannot set the brightness, only the start and omegle xender end time, see photo. I clicked mitras lb available under system and lighting. PL4 with FW 7.17 and GCC 1.1.1.8 What can I do? Restarting and reinstalling GCC also brought no improvement. Many greetings, Holger
