Events are not displayed correctly with resourcetimeline plugin

[rosanne-bzh]

my js is :

plugins: [ 'interaction', 'resourceTimeline' ],
views: {
	timelineThreeYear: {
    type: 'resourceTimeline',
    duration: { year: 3 },
    buttonText: '3 ans'
  }
},
locale: 'fr',
height: 400,
defaultView: 'timelineThreeYear',
aspectRatio: 2,
slotWidth: '20',
defaultDate: new Date(),
displayEventTime:false,
header: {
  left: 'prev,next',
  center: 'title',
  right: 'resourceTimelineYear,timelineThreeYear',
},
resourceLabelText: 'Salles',
      resources: [
    { id: 'a', title: 'Salle 1' },
    { id: 'b', title: 'Salle 1' },
    { id: 'c', title: 'Salle 1' },
    { id: 'd', title: 'Salle 1' },
  ],
  events: [
    { resourceId: 'a', title: 'All Day Event', start: '2020-10-01' },
    { resourceId: 'b', title: 'Long Event', start: '2020-10-07', end: '2021-10-10' },
    { id: 999, resourceId: 'c', title: 'Repeating Event', start: '2019-10-09T16:00:00+00:00' },
    { id: 999, resourceId: 'a', title: 'Repeating Event', start: '2020-10-16T16:00:00+00:00' },
    { resourceId: 'b', title: 'Conference', start: '2019-10-17', end: '2020-10-19' },
    { resourceId: 'c', title: 'Meeting', start: '2019-10-18T10:30:00+00:00', end: '2020-10-18T12:30:00+00:00' },
    { resourceId: 'a', title: 'Lunch', start: '2019-10-18T12:00:00+00:00' },
    { resourceId: 'b', title: 'Birthday Party', start: '2019-10-19T07:00:00+00:00' },
  ],

the result is :
