Events from Google Calendar showing at incorrect dates, or not showing at all

Edited: I have been using a Google Calendar of birthdays to test this module out. Sometimes events show up but incorrectly, like several months in advance although they seem to show up on the same day, as in an event created for the 25th of March will actually show up as occurring on the 25th of October for example.

{
        module: "calendar",
        header: "Calendario",
        position: "top_left",
        classes: 'default everyone',
        config: {
            maximumEntries: 5,
            maximumNumberOfDays: 100,
            calendars: [
                  {
                           symbol: "exclamation-circle",
                           url: "webcal://calendar.google.com/calendar/ical/cf9euqob2a0tqe2409jffnpk2o%40group.calendar.google.com/private-a8870caf6c3ca46a785e7fd1fec0dcb5/basic.ics"
                   }
                  ]
              }
}

Just FYI, my locales are set as follows:

LANG=es_ES@euro
LANGUAGE=
LC_CTYPE="es_ES@euro"
LC_NUMERIC="es_ES@euro"
LC_TIME="es_ES@euro"
LC_COLLATE="es_ES@euro"
LC_MONETARY="es_ES@euro"
LC_MESSAGES="es_ES@euro"
LC_PAPER="es_ES@euro"
LC_NAME="es_ES@euro"
LC_ADDRESS="es_ES@euro"
LC_TELEPHONE="es_ES@euro"
LC_MEASUREMENT="es_ES@euro"
LC_IDENTIFICATION="es_ES@euro"
LC_ALL=

@Txukie it may not be a good idea to post link to your private calendar in a public forum.

Since this all has to do with the ical parser, I suggest we continue this issue discussion in: https://github.com/MichMich/MagicMirror/issues/1105
