Missing translation error in section customisation area

I created a new liquid file and named it about-image-with-text.liquid, and I copied/pasted the code in the original image-with-text.liquid to the new about-image-with-text.liquid then I replaced all “image-with-text” in the new liquid file. I did the same thing for the relevant css files by creating new component-about-image-with-text.css, copied/pasted from component-image-with-text.css and updated the class names.

The reason I did the above is that I want to use Image with Text section in other pages however since I altered CSS, the style of the section is set globally across the pages, and I need them to be different.

The new section can be added to other pages successfully, however I encountered this Missing translation error in config/setting area as shown in screenshots.
