WAVE issues from homepage

Running WAVE on Discourse hosted reveals a handful of WCAG accessibility issues.
Posting each in a separate #ux thread.
Hopefully these are repeatable using WAVE on your own instance, but if not I can provide details on any of these items.

For the homepage:

Issue found Guideline Found by Notes WCAG Level
Empty table header 1.3.1 Info and Relationships WAVE table header contains no text A
Image with title 1.1.1 Non-text Content WAVE 5 instances A
Missing first level heading 1.3.1 Info and Relationships WAVE A
Redundant title text WAVE Not sure if this is discourse issue, or with component “Brand Header Theme Component”
