local build showing different format than CI build

If I trigger build on gitlab, I end up with an artifact which always shows the version + a part of the commit hash like `0.3.4+05bab3e2`

If I build locally I get the short version like `0.3.4`

hbs:
```
{{app-version versionOnly=true}}
```

command is `ember build --environment production` in both cases

What I noticed is that the builds artifacts differ in their index.html. Both have a meta tag which contains the version information. However the CI seems to populate the `version` field with data from `package.json` and the local build seems to use the git tag. The `code_version` field is identical on both. Just noticed because I was using a new tag but kept the previous version in package.json

Any ideas what might be happening or how to get the short format without the commit hash within the CI build on gitlab?
