`issues_access_level` is not considered when creating a new project


I’m running version 12.6.3 of Gitlab CE.
The API documentation (https://docs.gitlab.com/ee/api/projects.html#create-project) for creating a new project says, that issues_enabled is deprecated and issues_access_level is its replacement. I tried this, but the issues_access_level just seems not to work. Here the request to create a new project:

curl -X POST --header "PRIVATE-TOKEN: **************" "https://********/api/v4/projects?path=test4&namespace_id=342&issues_access_level=disabled"

The returned json then clearly says:

  "issues_enabled": true,
  "issues_access_level": "enabled",

Also on the project itself the issues are still enabled.

What am I doing wrong here?

Same here with v12.8.1. Did you solve your issue ?
