Small errors in the wp-content/plugins/download-monitor/assets/js/reports/reports.min.js file which is a minified version of reports.js Lines 535 to 550 are like this in the original file:

		// Get all dates from the startDate to the endDate
		let dayDownloads = dlmReportsInstance.getDates(new Date(startDate), new Date(endDate)),
			doubleDays, doubleMonthDownloads, weeksDownloads, weekDownloads;

		// Let's initiate our dlmDownloads with something
		switch (dlmReportsInstance.chartType) {
			case 'months':
				// Get double selected months
				doubleMonthDownloads = dlmReportsInstance.getDoubleMonths(dayDownloads);
				dlmDownloads         = doubleMonthDownloads;
				break;
			case 'month':
				// Get selected months
				let monthDownloads = dlmReportsInstance.getMonths(dayDownloads);
				dlmDownloads       = monthDownloads;
				break;

Fixed it by making these changes:

		// Get all dates from the startDate to the endDate
		let dayDownloads = dlmReportsInstance.getDates(new Date(startDate), new Date(endDate)),
			doubleDays, doubleMonthDownloads, monthDownloads, weeksDownloads, weekDownloads;

		// Let's initiate our dlmDownloads with something
		switch (dlmReportsInstance.chartType) {
			case 'months':
				// Get double selected months
				doubleMonthDownloads = dlmReportsInstance.getDoubleMonths(dayDownloads);
				dlmDownloads         = doubleMonthDownloads;
				break;
			case 'month':
				// Get selected months
				monthDownloads = dlmReportsInstance.getMonths(dayDownloads);
				dlmDownloads       = monthDownloads;
				break;
