html issue

Hello,
Actually I have the issue in all my articles.

When i create meow galleries, the html code turns into this :

<!-- wp:meow-gallery/gallery {"images":[{"alt":" visiter prague weekend","id":16041,"link":"https://voyageursgourmands.fr/visiter-prague/visiter-prague-weekend-1/","url":"https://voyageursgourmands.fr/wp-content/uploads/2015/11/visiter-prague-weekend-1.jpg","caption":""}],"layout":"cascade","htmlPreview":"\u003cdiv class='mgl-cascade-container'\u003e\u003cstyle\u003e\n\n\t.mgl-cascade {\n\t\tdisplay: block;\n\t}\n\n\t#mgl-gallery-61b27f52741be {\n\t\tmargin: -5px;\n\t}\n\n\t#mgl-gallery-61b27f52741be .mgl-box {\n\t\tpadding: 5px;\n\t}\n\n\t@media screen and (max-width: 600px) {\n\t\t#mgl-gallery-61b27f52741be  figcaption {\n\t\t\tdisplay: none\n\t\t}\n\t}\n\n\u003c/style\u003e\n\u003cdiv id='mgl-gallery-61b27f52741be' class='mgl-gallery mgl-cascade is-animated zoom-out captions-hover-only' style=''\u003e\u003cdiv class=\u0022mgl-row mgl-layout-1-o\u0022 data-cascade-layout=\u0022o\u0022\u003e\u003cdiv class=\u0022mgl-box a\u0022\u003e\u003cfigure class=\u0022mgl-item\u0022\u003e\n\t\u003cdiv class=\u0022mgl-icon\u0022\u003e\n\t\t\u003cdiv class=\u0022mgl-img-container\u0022\u003e\n\t\t\t\t\t\t\t\u003cimg width=\u0022770\u0022 height=\u0022514\u0022 src=\u0022https://i2.wp.com/voyageursgourmands.fr/wp-content/uploads/2015/11/visiter-prague-weekend-1.jpg?fit=770%2C514\u0026amp;ssl=1\u0022 class=\u0022wp-image-16041\u0022 alt=\u0022visiter prague weekend\u0022 loading=\u0022lazy\u0022 /\u003e\t\t\t\t\t\u003c/div\u003e\n\t\u003c/div\u003e\n\t\u003c/figure\u003e\n\u003c/div\u003e\u003c/div\u003e\u003c/div\u003e\u003c/div\u003e"} -->
[gallery ids="16041" layout="cascade"][/gallery]
<!-- /wp:meow-gallery/gallery -->

I don’t think this is supposed to be, and as an SEO expert, this is really bad to have for every single picture.

I tried to put only :

<!-- wp:meow-gallery/gallery -->
[gallery ids="16041" layout="cascade"][/gallery]
<!-- /wp:meow-gallery/gallery -->

This works a little bit, but if i go back to the article for one reason, the gallery is KO…

Can you help ?

Thanks a lot

Cecilia
