Bug? Wrong info in "Incoming Chages" CodeLens indicator

I am using VS 2015 and there is strange behavior WRT Incoming changes indicator. Let's say:

1. I have Class1.Method1 in the Main Branch
2. I create a new branch from Main called BugFix
3. I fix a bug in BugFix branch
4. I merge changes from Bugfix to Merge
5. Later on I delete (not destroy) the BugFix branch.

Now, my Incoming Changes indicator shows 1 incoming change on Class1.Method1 in Main branch and all other methods - it is the branch deletion! While I understand this is "logically" correct, it makes the indicator useless - it show MANY false positives during course of time...

I do not want to destroy branches or remove branch relationships, we delete branches just to make the Source Control Explorer UI clean and indicate there is no more work on the branch ...
