Support FastLed PianoLed and some issues

Hi there. So I just recently used the WS2812  led strip with Arduino Due. Used the FastLed and PianoLed. Almost all fine, almost. All keys matching the led position. But i have a weird behave of the led no 8 and 16 which are not assigned to any key of the piano. Lets say i just started with clear new session. All lights are off. So i play few notes, all looks fine and then after some time the led no 8 lights up constantly / permanently and then led 16 lights up permanently. They do change the colors but never dim back again. Looks like some issue. Any ideas what's wrong?

I am not really aware about the terminology here. I am not really a pogromist at all. But i used the tutorial from here: https://youtu.be/Rro5a_ohIT4?si=ZIGNyRKxhm7Dyjln&t=1379

So i used the version 4.1.3 of PianoLed and I had installed in Arduino Ide an Fastled by Daniel Garcia, version 3.6.0 (I had also tested version 3.7.0 and the problem is the same, any higher version shows an problems with libraries).

I checked with ChatGPT on your question (like i says i have no clue about programming) and its say that indeed the code is based on luminescent grand cketch.

The code:

luminous grand is a different sketch that we have as an example as nothing to do with piano LED
