multiple Lightpacks, Libreelec, RPi 3 - color problems

Hello everyone,

I already tried it in the German Forum part but since no one reacted to my post I try my luck in english

So I bought a RPi 3, installed Libreelec and set up Kodi with SSH support. Now I was trying to get my 2 Lightpacks running but still struggle to find the correct settings.

As of now i created a config with Hypercon but the colors seem to mismatch. I tried it with a wallpaper with a color gradient to the corners (up left - blue, up right - green, bottom right - yellow, bottom left - red). It seems like only the top part colors are registered and are shown around the whole TV.

I also tried to send only 1 color to all LEDs which worked perfectly fine so it seems that it has to do with the grabber itself...

I have 60 LEDs in total (2 Lightpacks @ 10x3 LED stripes) and at the bottom of the TV I only have 1 strip bottom left and bottom right with 3 LEDs each. But that should be no problem as I configured it as shown in the following screenshots:

I'm quite new to the whole RPi thingy and do not know what to do now. Is anyone seeing some false settings I made?

I did NOT install the Hyperion addon via Kodi as I read that this shouldn't be done.

Hope you get the point as english is not my native language

Thanks in advance!

I somewhere read that the 3 leds on each stripe are not able to communicate seperate to each other so does that mean I have to configure 20 instead of 60 LEDs? That would make sense to me...
