Milestones are removed when issues are added from the AeroTools/Backlog

[heikoklein]

Describe the bug
Adding issues directly in the Backlog is very convenient because the milestone and project are automatically set.

When adding a pyaerocom issue through the Backlog, the milestone is set for a couple of seconds, and then the milestone is removed by some internal automation.

Expected behavior
Automation should not remove the milestone of a project if set during creation.

Screenshots

github-project-automation removed milestone while adding AeroTools/Todo

This seems like a bug in GitHub's automation, not something we can control.
