Itamar, I believe this is a YAML limitation. See this GitLab issue as reference.
The problem is that you have two jobs with the same name. But when the YAML file is parsed, you're actually overriding the first job.
Also, from the official GitLab documentation:
Use unique names for your jobs. If multiple jobs have the same name, only one is added to the pipeline, and it’s difficult to predict which one is chosen
Please, try renaming one of your jobs and test it again.
