I have a recurrent issue with our Gerrit.
Merging some commits makes other commits show a merge conflict even when there are no conflicts at all. Gerrit shows the following message: Not current, rebase possible.

This issue can be fixed by just rebasing the commit (manually or using the built in rebase button) but I don't understand why is Gerrit complaining in the first place. There's no conflicting files, just the parent has been changed. Can someone point me in the right direction for this? Is this behaviour correct or can I change something in the Gerrit config to avoid this?
Rebasing is not a big deal but this causes all the hooks to run again and forces to review the commit again without any change.
Thanks,
Dani
