Our YAML rules are regarded as yml, and they can't be activated in the YAML quality profile

We write some YAML custom rules, however, our YAML rules are regarded as yml language, not YAML:

As the image above shows, our YAML custom rules have YAML tag, however, they are not included in the YAML rules, but yml rules.

And here comes the problem: we can only create new quality profiles for YAML because there is no choice to create yml quality profiles, and therefore our custom rules can’t be added into the quality profile. We can’t find them when trying to activate more rules in YAML quality profile.

So is there any way to create yml quality profile or make our rules regarded as YAML rules? Thank you.

By the way, our sonarqube version is 9.6.1.59531. We also try it on another sonarqube server which version is 8.9.6.50800, and it is ok. They are regarded as YAML rules and we can activate them in YAML quality profile in 8.9.6.50800 sonarqube.
