feature image credit appears within excerpt text

Hi,
I use the extension https://fr.www.ads-software.com/plugins/better-image-credits/ to display image credit (also on featured images).

In the excerpt this credit is not displayed at the bottom of the photo, as on the post page, but within the excerpt text.

See example of excerpt on home page : https://editionsisabellesauvage.fr/ (scroll to “Kamau Brathwaite”)

and the post page : https://editionsisabellesauvage.fr/kamau-brathwaite-2/

Since this part of the excerpt text is not styled I cannot put a “display:none” (as a bypass)

Thanks
