Dashboard not showing latest version on an environment

We seem to have a mismatch in the latest version on our QA environment when comparing the projects overview page and the main dashboard. We are on version 3.11.11.

seeing this error under diagnostics:

found the issue, we were testing out creating projects from our own api and a project must have been misconfigured. Deleting said project resolved the issue.
