Duplicate version in changelog

Describe the bug I've just started using standard-version in a new project. I generated the first CHANGELOG for version 1.0.0 with --first-release. Now I tried to release a new (minor) version but I noticed that the entire chapter for version 1.0.0 got generated again. Now I got it twice in my CHANGELOG.md.

Current behavior standard-version does not start collecting changes from the last release but from the beginning again

Expected behavior No duplicate versions in the CHANGELOG

Environment

• standard-version version(s): 9.3.2
• Node/npm version: Node 14
• OS: macOS 11.6

Additional context My versionrc:
