LED's on LFO3 won't light up

[nrgy]

Hello, When I press the select button to choose LFO3, and then Press select again to go down on "osc1,osc2,PW1,PW2 & sync phase on the LFO3 section, they wont light up. Only when I do a change and save it. But when I scroll between thoose functions I can see no light. The LED's work on the other LFO's/MOD, just wondering....this shouldn't be like that?
Not that it does any harm for me, but I was just wondering/& if anyone else have had the same problem?

Thanks
