Using dotnet-gitversion 6.0.5 and its not calculating the correct SemVer. Help

[llyons]

Hi, I am implementing gitversion for semantic versioning

i have these labels for a curent application on a "development" branch treating it as mainline

Onlife.Services.Settings.ApiClient-v3.1.7
Onlife.Services.Settings.ApiClient-v3.1.8

i have this gitversion.yml

strategies:
  - MergeMessage
  - Mainline
commit-message-incrementing: Enabled

tag-prefix: 'Onlife.Services.Settings.ApiClient-v'

branches:
  development:
    regex: ^development$
    increment: Inherit
    prevent-increment:
      of-merged-branch: true
    track-merge-target: true
    source-branches: ['development']
    is-main-branch: true

  pull-request:
    regex: ^(pull|pull-requests|pr)[/-]
    increment: Patch
    source-branches: ['development']
    track-merge-target: false
    label: pr


major-version-bump-message: 'BREAKING CHANGE(\(.*\))?:'
minor-version-bump-message: '^feat(\(\))?:|^feat(\(.*\))?:|^feat:'
patch-version-bump-message: '^fix(\(\))?:|^fix(\(.*\))?:|^fix:'

i am assuming if I run dotnet-gitversion /config gitversion.yml /output json that I would have 3.1.8 calculated as the SemVer but instead i get 3.2.0

{

"VersionSourceSha": "909a99a90f900a98e6f0070fb28b8512a5f68580",

}

What am i missing and with no new commits why wont it calculate 3.1.8

thanks in advance
