Preview and message disagreements

Preview (hovering the cursor over thread title) shows half dozen lines, and an attempt at answering poster's question; when I open the thread I get a first post that's one line long with none of the preview detail. This thread was duplicated in HW help section --- is there something happening to duplicates when they're removed/merged?Quick edit, found the duplicate

https://www.physicsforums.com/threads/hydrogen-bond-strength.784232/

and it's got the same "long preview" but short when actually opened behavior.

I just get the actual post content as preview. Maybe some cache issue?

And I don't see a thread in the homework section.

Just reloaded, and things are working --- we'll call it cache. The duplicate was in Physics rt. HW --- my bad.

Thanks.
