I can't seem to find a pattern that explains what I'm seeing. If necessary I can cobble together a screen shot upon request.
Edit: Here's a screenshot.
If you're talking about how the row is highlighted, that's because "bug" is a favorite tag of yours and that question uses that tag.
If you're talking about the "status-deferred" tag, that's because it's a special "moderator-only" tag.
They are tags that are commonly used on all StackExchange websites meta sites. They are primarily used to express the SE developer's response to requests, etc. (hence status-complete, etc.)
