The WordPress admin bar is showing inconsistently when

The WordPress admin bar is showing inconsistently when I'm logged in as a Q&A user. It does NOT show on non-Q&A pages (which is expected), nor on the Questions tab. It DOES show on the Answered tab and the Ask a Question tab.

Could someone please fix or explain the rationale? I can't implement, as this inconsistency is confusing for the user, who has no other reason to be logged in on my site.

Thanks
