Unavailable* room bug

When entering meetings into the Book-a-Room database for my Library’s WordPress yesterday I encountered an interesting bug. Any day within the allowed reservation buffer window, or beyond the days allowed to reserve window (defaults ‘2’ and ’90’, respectively), that has two or more reservations on that day will only show one of those reservations and show every other time-slot as ‘Unavailable*’. However if setup and cleanup increments are enabled those time-slots will display as intended even though the meeting they come before and after does not display at all!

I believe this to also be affecting the Height’s Library meeting reservation pages, however you may not have noticed if staff are logged in with admin privileges when checking as only readers and non-admin staff are affected by this bug. Anyone with Administrator privileges in WordPress will see all meetings displayed as intended when logged-in with no time-slots marked as ‘Unavailable*’. As a workaround I have set my Library’s page to -1 buffer and allowed reservations up to 365 days out, but if possible a fix for this issue would be appreciated. Screenshots of the bug in action are below.
