Hello,
We have the same problem with GitLab Enterprise Edition 17.11.0-pre 0c54ac72e29
It seems to happen when we cherry-pick a commit from a branch and want to merge it into an another branch that has diverged from the source branch (typically during a backport or forwardport). The MR default name seems to take the name of the first commit after the branches separated.
Any idea of parameters or anything to change this ?
Best regards,
Juliette
