If you are setting the cuepoints in XBVR then you need to tell Heresphere to refresh that information from XBVR to get those cuepoints to show up on the bottom of a video.
It is hard to describe maybe it is in the manual. I do it by accessing the xbvr website using the Heresphere web browser.
In HereSphere interface there is a little cogwheel in the bottom right corner once the XBVR interface is loaded.
Clicking it, I activated “Overwrite tags” which made HereSphere pick up the XBVR tags. The cuepoint tags are now visible above timeline of the vid being played.
