Patch version does not increase when commits are made to feature branch in MainLine mode of GitVersion

I am trying to figure out the simple Mainline developement mode.

My observation is the following.

1. Each direct commit on the master branch is incrementing the patch version.
2. When I create a feature branch, and then when I make commits on this feature branch, the patch is not increasing. I am wondering why? Only the PreReleaseTag is increasing. Example featureBranchName.1, featureBranchName.2 and so on for each commit. Patch does not change.

Why does not the patch version increase when commits are made to feature branch? Does a feature branch always imply a prerelease?

Is there a way to increase the patch on commits to feature branch?

My GitVersion.yml file is below. The -diag output follows, if that helps.
