(Sorry for any grammatical mistakes.)
My friend and I did the same steps below by SourceTree:
- create a feature named "TEST-1234_AAAA" from Develop and switch to it
- edit a file and make a commit
- push "TEST-1234_AAAA" to our Git server
- finish and delete "TEST-1234_AAAA"
Somehow we got different results,
my feature on remote was still alive, but his got deleted.
Here is my output message during feature finishing:

and here is his output message:

Is there any option or setting can cause the difference?
I would be thankful for any help.
