Using multiple UARTs on Teensy?

[ghost]

I've been working on a new breakout board for the Teensy 4.1, however recently I've hit a snag trying to use two UARTs, I'd like to be able to define and use Bluetooth on Teensy UART1 Pins 0 & 1 and Modbus RTU on Teensy UART8 Pins 34 & 35. I have rewritten a new version of the Uart.c file to support a second UART however when I compile and upload to the Teensy with both Bluetooth && Modbus Enabled in the my_machines.h, only Modbus is listed in IO Sender. The weird thing is that it assigns Modbus to Teensy UART1 Pins 0 & 1, but when I $pins the other UART8 shows up with the correct pins assigned as UART, but no Bluetooth? Any ideas, would be greatly appreciated I've tried everything I can think of with my limited coding skills.
