Any other clue about the problem? is it reproducible? which steps?

Also, it'd be appreciated more descriptive names in the issues and PRs, and therefore in the branches' names. For the branching we are using the Oneflow way: https://www.endoflineblog.com/oneflow-a-git-branching-model-and-workflow#the-main-branch.

with prefixes feature\ , fix\ , release\ and test\ (i think i do not miss any other one)

I'll check if this is included in the contributing documents, in order to clarify it. Thanks for your contribution!
