Hello, @Carlos,
Actually, it was nothing but just a cache issue. I just clear the cache from the plugin settings and your issue was resolved. Check this image first: https://postimg.cc/tntHqsk0 and now check the resulting image here: https://postimg.cc/vDHRfZ0m and now please watch this video: https://streamable.com/o213vk
The cache got strong on your server so every time you make changes from the backend admin dashboard of your site you must have to clear the cache from the plugin settings as I did so that the change will appear on the site.
