Monthly List View Rendering "aru6" instead of day dates

[rico161]

When enabling the Day labels in list view, for some reason instead of displaying the date of the day for each group of events, the link text is being rendered as the string "aru6" instead of the date numbers. The day label correctly shows the day name (saturday in the screenshot below). It looks like the actual link destination even goes to the correct date as shown in the code screenshot, but the actual text of the link always just says "aru6" no matter what the date is.

This is a weird bug that i couldn't find any fullcalendar documentation on, so i'm not sure if it's just specific to this build or fullcalendar in general.

Does aru6 appear for only Saturday or does it appear for other days with different number increments 1, 2, etc?
