Bug Description

I am using Fullcalendar in React and RRule for recurring events. The problem occurs in any view, but for this case, I will focus on the dayGridMonth view. The issue occurs with any type of repetition, but for this case, the repetition is set to every week. When I resize or drag the event while in the month it was originally created in, everything works fine. However, when I change to a different month and resize or drag the event, all events that were not visible in the original month disappear. I have attached an explanatory image.

Hey Guys,
this happens in Angular as well.
Should I provide a minimal example
or is the underlying issue the same?

Fixed in v6.1.5

I converted the original buggy repro to stackblitz because codesandbox never works for me anymore:

Here's an updated WORKING repro that uses 6.1.5:
