Not able to select my branch in ready api

Hi,

I have created a new branch through Azure portal example 'Test'. 

1. Open ready api
2. Clone the same branch to ready api
3. project created on the Left
4. Click the icon 'Opens the GIT panel ', it will open the small panel window on the right
5. Under the 'Changes' tab, select the drop down which shows my new branch 'test'
6. Whilst selecting my branch , pop up window displayed

   7. Just to consider its a new branch , I haven't made any changes yet.

   8. Clicked 'Discard Changes and continue'. It will say reloading the project and the project on the left will disappear. I have to go File> Recent>Removed Projects.
7. 9. I can see my project in the removed projects . Click from there to load back.
8. pop up window to configure GIT. Clicked 'use account' and then clicked 'select'
9. Again clicked on the icon to open the git panel. I can see the main project selected in the drop down
10. I will try to select my branch 'test' and then it goes in the loop with the same pop up 'There are uncommitted changes that will be lost'.
11. Please help. I am not able to work on the branch i have created.
