[TYPO3-calendar] image caption in event view

[Silvia]

Hi,
the caption of the image in event view does not show up.
What can I do? I already tried so much.

Typo3 7.6.15
Cal 1.11.0

Thank you for any help
Silvia

 From the documentation i inserted in setup:

plugin.tx_cal_controller.view.event.event {
	image {	

		textPos.override = 17
		layout.key.override = 17

		1 {
			altText.override.field = imagealttext
			titleText.override.field = imagetitletext
			caption.override.field = imagecaption
		}
		imgMax = 4
		imgList >
		imgList.override.current = 1
		imgPath = {$plugin.tx_cal_controller.uploadPath.image}
		stdWrap.dataWrap = 
<div>{LLL:EXT:cal/controller/locallang.xml:l_event_image} |</div>
		stdWrap.required = 1
		1.imageLinkWrap.enable.field >
		1.imageLinkWrap.enable.override = 1
		maxW = {$plugin.tx_cal_controller.singleMaxW}

		# switch to turn on the lightbox: kj_imagelightbox2

		# 1.imageLightbox2 = 1
      }
}
