aman204 thanks Aman. However, it's not just a problem of styling / formatting.
On article view, the masthead should show the article title, author, and publication date. But with the bug, after refreshing, it instead pulls up the category title and meta description (as shown in the screenshot you've provided).
In other words, it won't be solved just by adding some CSS - the JA Masthead module is clearly pulling in the wrong article data / parameters after refreshing.
Until recently, this wasn't happening (even with JCH Optimize installed), and the problem had been resolved with use of the System Page Cache plugin. Which makes me think there's a problem to be fixed with JA Masthead.
