Corne left side LEDs stop working when pairing to the host

[j1n6]

Describe the bug
Regarding to Corne pairs.
RGB LED does not work on the left side after pairing to a bluetooth host.

To Reproduce
Steps to reproduce the behaviour:

1. Flash the firmware, LEDs on both sides light up once as an indicator of firmware flash completion.
2. Press any key, the LEDs also light up on every key press.
3. Pair the Corne_L to the host on Mac
4. LEDs on the left side stop lighting up, right side behaves correctly
5. After unpairing the host, the behaviour is the same as step 2.

Expected behavior
Both side should light up on key press before and after pairing to a bluetooth host.

Desktop (please complete the following information):

• OS: macOS Big Sur
• Version 11
• BLE controller: Nice!Nano

Additional context
I might have mixed sk6812 and WS2812 soldered on the corner. The corne has been used over a year on QMK, thus I believe it shouldn't have hardware build issues.

Edit:
When the left side wakes up from sleep, LEDs flash once correctly then stops functioning.
