If that’s really the case it would be a bug and should be reported at the gitlab bugtracker.
But before doing so it would be good to attach the project in this thread, so we can confirm the behaviour (or find a different reason for the DRC-warning).
note: as a new user you are not allowed to attach files, you need at least the next forum user level. It would be good if you could read and follow this link: New Member Information.
If you fulfill the requirements (read at least 30 answers for at least 10minutes, in at least 5 different topics) you promote yourself to the next “basic user” level and are allowed to attach something to your posts.
