Expected behaviour

I would expect the titles of the various annotated posts displayed on H to be that of the tag on the annotated page or some other logical name based on a parsing algorithm.

Actual behaviour

The titles for almost all the annotations on my website (since 2016), regardless of the page they’re on, appear to be the incorrect title: “Top Ed-Tech Trends of 2015: Indie Ed-Tech”. The few exceptions seem to be the self-hosted .pdf files on my domain/storage that I’ve annotated.

Browser/system information

This appears to be browser and OS independent

Additional details

The only post on my website related to the title which appears seems to be which contains copies of the annotations I made on Audrey Waters’ page. See:
Some time around 2016 Audrey disabled annotations on her site (due to abuse, though it appears she’s since re-enabled them?). Is it possible that the H client has somehow cached the title of her post and is somehow mapping it as the title for all of the annotations made on my site? Having looked at the pages which have been annotated on my site, there’s nothing hiding in or related to the the meta data or rel=”canonical” links that would indicate that they should have the titles that H is finding for them.
