Other user code changes appear in my local repository

[Malcolm Briggs]

Hi Team,

We have a BitBucket server that we installed in our local development server 3 yrs ago. We use SourceTree to manage git actions and  and our git work flow is the simple trunk style repository for a very small team of four people.  

I tried to figure out why the change of other developer appear in my SourceTree. I couldn't resolve it. It is not a line endings issue that we see, it is proper code changes that other user made it. This causes a real issue. 

Thank you for your help and looking forward to a solution or a suggestion. 

Kind Regards,
