The event in the fullcalendar is not added to the next year

Question

When I add an event for the current year, everything works. And when I add on any date of the next year, it is not added, and error in console:

plugins.bundle.js:54 Uncaught TypeError: Cannot set properties of undefined (setting 'tabIndex')
    at V (plugins.bundle.js:54:16706)
    at I (plugins.bundle.js:54:12928)
    at L.b.setDate (plugins.bundle.js:54:32849)
    at populateForm (calendar.js?80967:931:22)
    at handleNewEvent (calendar.js?80967:438:9)
    at t.select (calendar.js?80967:145:17)
    at e.trigger (fullcalendar.bundle.js:20:82181)
    at mr (fullcalendar.bundle.js:20:48529)
    at n.handlePointerUp (fullcalendar.bundle.js:20:188907)
    at e.trigger (fullcalendar.bundle.js:20:82181)

I did not find information on this error on the Internet. I tried to change the order import scripts, but it does not help. I am using fullcalendar with metronic template.
