Board view doesn't show all cards when group by date

Body

Added five tasks and some randomly show up in the board view. If I add a new task, board view will sometimes show all or a few. If I refresh, then some random one (or none) will appear. This is a personal/private project. The tasks are not linked to any repo, no permissions setting, etc.

Filtering for the "unseen" cards doesn't show them either.

*Editing to add that I've tried on Firefox and Chrome and get the same behavior.
This only happens when Grouping and ONLY when grouping by a Date type field.

The "white" flashes is the page refreshing.

Indeed, grouping by date doesn't work at all.
