• I have searched Superset docs and Slack and didn't find a solution to my problem.
• I have searched the GitHub issue tracker and didn't find a similar bug report.
• I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section.

The "Today at LTS" display isn't expected behavior and doesn't come from any standard date formatting or fallback in the Superset codebase. The component responsible for this uses strict date formatting and the dayjs library, and there's no reference to "LTS" as a format or string in the code or recent changes for 5.0.0rc3. This suggests the issue is likely caused by something external to the main codebase—possibly a misconfiguration, a custom override, or an environment-specific problem (like a locale or timezone setting being interpreted incorrectly) rather than a bug in Superset itself. You might want to check for any customizations or overrides in your deployment, or if any libraries (like dayjs or its plugins) are mismatched or misconfigured in your environment.
