simple git flow breaks ungit

[Console32]

I was trying to create a graphical representation of our git workflow. I used the following commands to create the history

git init                                                              
git commit --allow-empty -m 'Initial commit'                  
git checkout -b dev                                           
git checkout -b features/A                                     
git commit --allow-empty -m 'implement feature A'         
git commit --allow-empty -m 'implement feature A'         
git checkout dev                                          
git checkout -b features/B                                     
git commit --allow-empty -m 'implement feature B'         
git commit --allow-empty -m 'implement feature B'         
git checkout dev                                          
git merge --no-ff features/A                               
git merge --no-ff features/B                                   

The resulting graph looks like this in my CLI:

But ungit shows:

I tried a fresh start - same result.

I am facing the same issue, with ver1.5.11 on windows 10, and ver1.5.13 on Debian 10.

This is what it looks like with #1315 :
