Hello,
I've been using Bitbucket for a long time without any issues, but for the past few weeks, whenever I try to make a pull request from a branch to my master branch, the web form that captures the PR description and name includes a lot of past commits, not just the ones that need to be merged. For example, if it needs to merge 2 commits, it lists much older commit comments, making it look like you're going to merge more than you should. In reality, it only merges the necessary files, but visually, the description is incorrect and it gives you quite a scare. I end up having to delete the commits I don't want listed every time.
