SourceTree commits with a different author name and email

Question

When I Commit from SourceTree it commits 
With an Author and Email different from what I have configured

Because I dont want to share my actual Email I will use an example that is identical

Lets say I have configured git as follows

git config --global user.name "Doe"
 git config --global user.email johnseDoe@example.com

When I commit from the command line or GitHub Desktop 
The commits are assigned to the correct Author Name and Email exactly as Configured

When I commit from SoureTree, it commits as 
"John Doe" and johnseDoe@exampleinc.com

So it changes the spelling of my Author Name and the Email Domain of my email, by adding INC

Now what is also weird, is that everywhere in SourceTree it only have the correct the one
Even in the commit section

I dont know what drive SourceTree to modify them the mometn it commits 
I googled this extensively 
I uninstalled SourceTree, deleted all the folders for Atlassian and SourceTree from the user folder (before reinstalling), I checked all the setting

Somehow SourceTree still manage to remember the wrong Author Name and Email

This is driving me a bit crazy, I tried everything I found online, nothing work, this is probably a deep bug in sourcetree
And it is concerning, since I dont know how else SourceTree could be changing things behind my back

I figured out what the issue, possibly a bug, was exactly

1. My HOMEDRIVE environment variable, points to network drive
2. If I am connected to the work network, .gitconfig gets created under my HOMEDRIVE env variable location
3. If I am working offline (i.e. not connected to work network) my .gitconfig  get created is the folder from the USERPROFILE env variable 
4. If you try to commit while a .gitconfig is missing, git will still commit and give you this warning " ... Your name and email address were configured automatically based on your username and hostname. ...."
5. The issue with ST is that the command line and all the tools were able to read from the .gitconfig under my USERPROFILE folder, while I am offline, only ST would treat it as missing 
6. What is even weirder, is that every else in ST like in options screens and changes screen, ST was able to read it fine, only while commiting would it behave like the file is completely missing

So the best solution i found which seem to fix all, was to set the env variable
GIT_CONFIG_GLOBAL to point to the .gitconfig under USERPOFILE

[System.Environment]::SetEnvironmentVariable('GIT_CONFIG_GLOBAL', $env:USERPROFILE + '\.gitconfig', 'User')

This way all the tools all the time will use this .gitconfig
