Hugo CI builds are generating incorrect GitInfo commit hashes

Hello! I am successfully hosting a static website in Hugo (v0.75.1) by using Gitlab Pages here: https://gitlab.com/singulari-org/ink.university

For some reason, CI builds for this site are generating incorrect GitInfo commit hashes for almost every page. The timestamp at the bottom of this page is one such example:

This doesn’t appear to be a Hugo problem. If I generate the site locally, timestamps are correct. If I generate the site by using the monachus/hugo Docker image, those are correct as well.

This leads me to believe that this is a Gitlab issue. Maybe a caching problem? I tried “hugo --ignoreCache”, but that did not help. Neither did clearing the runner caches.

Any other ideas? Your advice would be greatly appreciated.
