Kustom komponent issue

I've been using the SMonthCalendar for awhile now but just recently, the icons aren't properly showing. For example, in the editor I have a filled circle under each day representing the events I have for that day but they show as the letter 'b' and for navigation buttons to prevent and next month they're three ellipses but they show as the letter 'a'. I'm not sure if it's something in the editor or the komponent. I tried just reselecting and re-saving but it doesn't help.
