Hi @afmenez,
Thank you for working on cleaning up the misspellings.
Would you mind combining all the related changes into a single PR instead of opening multiple ones?
Also, it's recommended to make and test the changes locally, and then push all commits all together in one go to the PR.
Instead changing a string then push a commit.
It is because that the CI/CD pipeline runs jobs for every commit you push, which can hog a lot of computational resources.
You’re welcome to make as many commits as needed—just pushing them together

Hello @SoftFever,
I didn't open all these MRs at once, they were opened on different days along the last weeks. They are taking a long time to get in, so they accumulate.
And that's also why they break the builds, other merges enter first and cause conflicts, and sometimes they break when I fix the merge issues.
