Why does a reminder get duplicated in my Calendar?

Aholiab

When I input a reminder in the Calendar, it enters that value multiple times on the same date. This only seems to be a recent problem. As a result, I cannot use my Calendar except for previously entered reminders.

Anyone else experience this?
