Z Offset is not applied to prints

So I have been working on modding out my cr-10 using a duet wifi to make upgrades like dual lead screws and other things. I had everything working but then added a bltouch pin. I have been working at this for about 2 days now and have gone through all of the forums and the tutorials. The printer homes fine and I am doing the calibration sequence. But no matter what my input value is on the G31 command, nothing changes. I have gone through the forums already and checked my override and my M501 in the config. I'm just really stuck at this point and any help would be appreciated.
Here is my config:; Configuration file for Duet WiFi (firmware version 3)

Hi, your config file has a mix of version 2 and version 3 syntax for the probe and I think you're over writing yourself causing some issues.
Please tell us what firmware version you're actually using. Send M115 to find out. Once we have that we can clean up the config. In general, assuming you;re on RRF3, you should remove any references to
M307 H7 A-1 C-1 D-1and any M558 commands that don't have the zprobe.in pin part, as they are formatted for RRF2. You've also got a second G31 near the bottom with no offsets that would be over writing your previous command.Just going through the web configurator and choosing the Ender 3 as a starting point, firmware 3, and bltouch gives this as an example to compare against.

Hi,
We need to know how and when you create the height map AND how and when you apply the height map.
These steps involve G30 for setting the Z=0 datum and G29 for creating/loading the height map.
Both involve using the Z probe.

@Phaedrux Thank you so much for helping, I modified the config so now it works. I guess following multiple tutorials to try to make it work created some problems. I am currently doing the mesh leveling for the bed. Thanks again for your help.

No problem. It can get a bit daunting at times and we tend to overthink it which can lead us astray. Usually, when in doubt, getting a config from the configurator will show us the correct syntax to start with.
