Cannot find some branches when filtering them

[gh]

Hi,

We experience that when filtering branches on a part of their name most of them show up in the result list, but for some search terms we cannot find any results. However, when scrolling through the pull requests those branches show up there.

For instance, we have branch_123 and branch_456:

When filtering for branch_123, the result shows this branch. When filtering for branch_456 that one is not shown.

We regularly delete branches locally, but not on the server.

Version: Atlassian Bitbucket v6.10.0

Any idea?
