Migrated article loses images due to path change

I’m migrating to Softr. On my previous site, I have the path: domain/articles/

To migrate over I simple copied the page contents and inserted into a text block. However at first I made my page on softr domain/ which worked perfectly for content and images that copied over.

But I need to keep the same path to maintain my search engine results. So I updated the page path to be domain/articles/ as per this Softr recommendation:

However, the images are now gone, I guess the image paths don’t automatically update when changing the page URL. I need to update the article image paths.

Please help any tips appreciated. I would manually add the images back in, but I have a single text block and don’t see an image insert option.
