slider text translate in home page ( bwg-slider-description-text)

[B] text translation “description” slider on the homepage [/ b]:
Hello

I used the theme “exclusive”
and did the English version with the “Polylang” plugin
the translated home page was created automatically (from french to english)
the problem is: the text description on the slider(“bwg-slider-description-text”) remains in French on the English version,

in dashboard the home page is not inside the page list so it is not accessible.

I would like to insert the right code in the right php file (here c is a child theme) I have located the code with firebug but I do not know wich part of it to copy and paste in wich php file. every attempt added elements in the header.

thank you for your help [/ quote]
