It's more like cache issue.

--> Exclude logged-in users from cache

• Go to LiteSpeed Cache → Cache → Cache → [Logged-in Users]

• Make sure “Cache Logged-in Users” is disabled.

• Same for “Cache Commenters” if you have comments.

--> Purge all caches

• Go to LiteSpeed Cache → Toolbox → Purge

• Click “Purge All” and “Purge All CDN Cache” if available.

--> If it’s still broken

• Temporarily disable LiteSpeed Cache and CDN — does the bar show up?

• If yes, it’s 100% a cache/config issue — not WordPress core.
