CentOS 7 Cannot delete ports defined for MongoDB

I installed and later removed the MongoDB server on a CentOS 7 box.

While cleaning up, I noticed that the ports assigned to MongoDB were still open. if I remember correctly, I was able to delete the main port (28017), but there are still two ranges defined:

$ sudo semanage port --list | grep mongo
mongod_port_t                  tcp      27017-27019, 28017-28019

When I try to remove the ranges, I get an error:

$ sudo semanage port -d -p tcp -t mongod_port_t 27017-27019
ValueError: Port tcp/27017-27019 is defined in policy, cannot be deleted
$ sudo semanage port -d -p tcp -t mongod_port_t 28017-28019
ValueError: Port tcp/28017-28019 is defined in policy, cannot be deleted

I have looked for any modules referring to MongoDB, but there does not seem to be anything there:

$ sudo semodule --list # => nothing mongo-related

Is there any way to find out in which policy the ports are defined? Or is there some other way to remove these ranges?

Thank you.
