Node Version: what is this? how do I get this info?

MagicMirror Version: 2.16.0 (problem occured after upgrading from 2.13.0, problem still existed in 2.15.0).

Description: I show holidays with start and end dates. The shown config worked well with 2.13.0, after upgrading to 2.15.0/2.16.0 the end date disappeared. Now, only the current day of the current holiday is shown.

Steps to Reproduce: With my config in MM 2.16.0

Expected Results: start (or current) date AND end date "Sa 10. Apr. - Fr. 16. Apr."

Actual Results: only start (or current) date "Sa 10. Apr."

Configuration:

{
	module: "calendar",
	header: "Ferien Hessen",
	position: "top_bar",
	config: {
		tableClass: "medium",
		colored: true,
		fetchInterval: 900000,
		fullDayEventDateFormat: "dd DD. MMM",
		timeFormat: "absolute",
		urgency: 0,
		getRelative: 0,
		maximumEntries: 1,
		maxTitleLength: 50,
		showEnd: true,
		dateEndFormat: "dd DD. MMM",
		calendars: [
			{
				// Ferien Hessen 2021
				symbol: "democrat",
				color: "#ffbbbb",
				url: "https://www.ferienwiki.de/exports/ferien/2021/de/hessen"
			},
		]
	}
},

Additional Notes:
The option "showEnd" is shown two times in the Calenders doku with similiar descritions!
