In this image I've got the text in Strapi which is quill 1.6, here you can see I've added the lists.

Then here we have it being loaded in our front-end which is 2.0.0-rc.2

As you can see, it breaks the ordered list, and straight up removes the unordered list. This is a problem because we have a lot of data with the 1.6 editor that now needs to be used by the 2.0 editor. We can loose data this way.

Here is the code we use to read it in, in the front end.
