"Error: No Assets to Check In" warning when using File > Submit to Source Control on Mac SVN

When connecting to SVN source control on Mac, I am unable to submit new assets to Source Control using the File > Submit to Source Control method or through the Source Control > Submit to Source Control dropdown.

Source Control submission functionality still works as expected when using the Right Click > Source Control > Submit method.

1. Create a new folder on your Mac
2. Open a terminal at the location of the newly created folder, or open a terminal and path to the folder location
3. Enter

   svn co http://ENGQAAPP-01.epicgames.net:81/svn/EngineQATest/trunk EngineQATest --username first.last

   into the terminal

4. Inside the folder, find the EngineQATest.uproject and open it into the latest 4.12 Binary engine
5. If not connected to Source Control by default, connect to Source control using the following:
   1. Press the Source Control button at the top of the editor and choose "Connect to Source Control"
   2. Select Subversion as the provider
   3. Repository:

      http://ENGQAAPP-01.epicgames.net:81/svn/EngineQATest/trunk

   4. User Name: First.Last
   5. Labels Directory: ../tags/
   6. Password: Your AD password
6. Create a new Material and save it
7. Select File > Submit to Source Control

Results: Error message appears stating "No assets to check in!"

Expected Results: Window appears with newly created material in it asking for a changelist description for submitting the asset to source control
