Weekend Columns Display in Narrow, Vertical Column – Unreadable

On my main calendar, month view, the weekend days are showing in unreadable, narrow, vertical columns. My container is set to full width, and my calendar is set to display weekdays on the calendar and in the short codes section. My site is private. Thanks in advance for any help provided.
