Reply to loopsize+set output not working?

so i am on tpro2 and an apc20. everything on my mapping is working so far except for the looping section.

i want 8 buttons for the loopsize+set function from 32 down to 1/4.

32 16 8 4
2 1 1/2 1/4

input works like a charm, but i want visual feedback too. the buttons should light up when their value is set and active. they don't with the regular output function. the size-output works but doesn't satisfy as it ignores wether the loop is on or off.

there must be a simple solution to this!
