Strange Behavior of the Midi Feedback to an APC Mini

[DJTheBit]

Hi

i have a problem with the MIDI feedback to an APC Mini. I use the left / right button as external control the next/previous page command. The Frame has 4 pages and in all pages the 64 buttons and 8 slider are mapped to the APC. This works right, but not the LED of the left / right button. If the 1st or 2nd page open the left / right button LEDs are off. On the 3rd ond 4th page the LED of the right button lights up. If i go back to page 1 and then from page 1 to page 2 the LED of the right button switches off. It doesn't matter what i set up in the custom feedback. I tried it with 1 and 1 in lower and upper value also with 0 and 1, 2 and 2 and so on. The Midi message is always the same:

for right button (from 1 to 4)
90 43 00 Note on G3 Velocity 0 Channel 1
90 43 01 Note on G3 Velocity 1 Channel 1
90 43 01 Note on G3 Velocity 1 Channel 1
for left button (from 4 to 1)
90 42 01 Note on F# Velocity 1 Channel 1
90 42 00 Note on F# Velocity 0 Channel 1
90 42 00 Note on F# Velocity 0 Channel 1

If Data1 is 43 and Data2 01 the LED lights up and if i step from page 1 to page 2 the LED switches off

I have tested it also with more than 4 pages and found out that the Data2 value depends on the page numbers
page 1,2 : 00
page 2,3 : 01
page 4,5 : 02
page 6,7 : 03
.
.
.
and so on

The issue only occurs on the next / previous page control. If i set the left / right button from the apc as external control to an standard button LED off / on works with 1 in lower value and 2 - 255 in upper value
I'm looking for a solution that the LED is permanently switched on if i use the buttons to control the pages
