Let me confirm my understanding of the original problem:
Hello, I have been trying to program my BL Touch for over a week now and when I run M558 it shows profile as 0
I took this to mean that if you send M558 without parameters, it says the probe type is 0. Is that right?
Which firmware version are you using? Probe type 9 was added several months ago, but if your firmware is very old then it won't support probe type 9.
I am currently on 1.21

What do you have in your deployprobe and retractprobe macro files?
Does the probe respond to M401 and M402?
The zProbe box in the DWC is not an accurate way to test the BLTouch because of the way that it triggers and instantly resets. The display may briefly flash to 1000 and then immediately go back to 0.
If the probe responds to M401 and M402, try doing a dynamic test by positioning the head far above the bed and issuing a G30 command to start a probe move. Trigger the probe pin by hand. If the movement stops, you're good to go. If it doesn't stop, kill the power to stop movement, and double check your wiring, because something isn't connected right.
it does respond to M401 and M402 but when I do a G30 it will just bring up manual bed compensation pop up

M574 Z1 S2 ; Set endstops controlled by probe
I added the M574 command and changed the value to 25 and still no luck, it responds to the testing commands though.
I removed that line and still getting the same issue. It is still coming up with the manual bed probing also

Hello, I have been trying to program my BL Touch for over a week now and when I run M558 it shows profile as 0. In the config though it is showing the correct profile, I have also noticed on the web interface that the sensor box under machine status is Vin 24.4 V and Z-Probe 0 and will not change from that.
