File list displays in reverse alphabetical order

SourceTree does not display the list of files using the 'Sort by' option I last selected. It retains it but always defaults to showing the paths and files in reverse alphabetically order. 

I've search high and low and don't seem to find a solution to this. Hoping that I missed a setting or something.

I would consider this to be a severity level of Major. More of an annoyance than anything else.

Steps to reproduce:

1. Select the file/path sorting method

2. Click on a commit. Make sure you have more than one folder and multiple files at each node in the tree

3. The list of files are displayed alphabetically but in reverse

4. Change the Sort by to Path Alphabetically (reversed). The list remains in the same order

5. Change the Sort by to Path Alphabetically and it displays properly

6. Change to a different commit and it begins all over again
