Found the culprit, it due to the source of image, when you edit a page, you should add a slash in the image path: https://prnt.sc/tmg1h7
For example, instead of this: media/jub/images/default/logo.png
It should be: /media/jub/images/default/logo.png
You need to apply the same for other images.
I made a sample on this service page and it works now: https://vicmobilemechanic.com.au/services/ac-service
