MMM-CalenderExt2: fullday events not displayed on day of event

[evroom]

Hi,

I recently started using MMM-CalenderExt2 due to issues with the default calendar, but with this module I have the following problem:

Full day events are not displayed on the day of the event.

I use Google Calendar to enter the event (full day event for today):

BEGIN:VEVENT
DTSTART;VALUE=DATE:20200502
DTEND;VALUE=DATE:20200503
DTSTAMP:20200502T102951Z
UID:329p3d2e5fccimqrsfjl6c6g9e@google.com
CREATED:20200502T102356Z
DESCRIPTION:
LAST-MODIFIED:20200502T102356Z
LOCATION:
SEQUENCE:0
STATUS:CONFIRMED
SUMMARY:ALLDAYTEST
TRANSP:TRANSPARENT
END:VEVENT

On the MM I do not see the event.
When I enter a full day event for tomorrow, I see the event scheduled for tomorrow.
Then after the first refresh of the events on the day of the event (approx. at 00:05 hrs), the event is removed from the list of events for that day.

Very annoying.
Any ideas how to get this fixed ??
Is this a parsing issue, or a module issue ??

Part of config.js:

views: [
      {
        name: "Familie Calendar",
        mode: "upcoming",
        position: "top_left",
        calendars: ["Familie Calendar"],
        slotCount: 1,
        slotTitle: "Family Calendar",
        slotMaxHeight: "16px",
        filterPassedEvent: true,
        maxItems: 9,
        maxDays: 60,
        locale: "de-DE",
        hideOverflow: false,
        dateFormat: "ddd Do MMM",
        dateTimeFormat: {

                nextWeek: "dddd HH:mm",
                lastDay: "[Yesterday] HH:mm",
                lastWeek: "[Last] ddd HH:mm",

                },
        timeFormat: "HH:mm",
        relativeFormat: {
                passed: "ended %ENDFROMNOW%",
                current: "ends %ENDFROMNOW%",
                future: "starts %STARTFROMNOW% (%DURATION%)",
                },
        useEventTimeRelative: false,
        transform: (event)=>{
          if (event.title.search("Verjaardag") > -1) {
            event.icon = "fxemoji-partypopper" // Set icon of that event to "fxemoji-partypopper"
          }
          if (event.title.search("RIP") > -1) {
            event.icon = "fxemoji-whitelatincross"
          }
          return event // Return that event.
        },
      },
    ],
