As I continue to research this, I did find something that might have solve this issue. I will try it out today.
On the doc pages: Channel - Role:
it says:
While you can have a different PRIMARY channel and communicate over SECONDARY channels with the same Name & PSK, a hash of the PRIMARY channel’s name sets the LoRa frequency slot, which determines the actual frequency you are transmitting on in the band. To ensure devices with different PRIMARY channel name transmit on the same frequency, you must explicitly set the LoRa frequency slot.
Will report back if this solves the issue.
