Build badge not displaying correct status

My badges aren't displaying the correct status, as in:

• https://gitlab.com/middleman-themes/middleman/badges/master/build.svg - [build | skipped] - but build passed;
• https://gitlab.com/themes-templates/hexo/badges/master/build.svg - [build | running] - but build passed;

there are others too.

Am I using the correct path?

https://gitlab.com/namespace/project/badges/branch/build.svg

Possibly related to: https://gitlab.com/gitlab-org/gitlab-ce/issues/13286 https://gitlab.com/gitlab-org/gitlab-ce/issues/5570 https://gitlab.com/gitlab-org/gitlab-ce/issues/13559 https://gitlab.com/gitlab-org/gitlab-ce/issues/13801

Note: I'm sorry if shouldn't open a new issue, but I've seen there are many issues and MRs related to this subject, so I don't know where should I report this!
