problem with enfold theme — problem for seo-image

Hi !
for my seo, i use yoast and i have a problem with enfold theme — problem for seo-image

yoast write to me :

. Portfolio Images on Sitemap
Yoast outputs images on your sitemaps. However, your portfolio sitemap https://………/portfolio_entries-sitemap.xml does not have the images. This is because of your theme. Yoast is not compatible with every pagebuilder plugin or theme like Enfold. If the plugin/theme has added the right code for Yoast to hook into, Yoast is expected to then scan those modules for the images and add them to the sitemap. We are not familiar with that plugin/theme so we are not sure if they have added the right code. We suggest contacting the plugin’s/theme’s authors and asking them if they have included the right code in all the modules for Yoast to scan.

Have u a solution ??? or do i have tu use Gutenberg wordpress ?

thank fir ur answer
