Strange behaviour of ordered lists

I have an ordered list within another ordered list. Such as

  1. Item one
    a. some test
    b more text
  2. Item two

The HTML and preview look ok in Live Composer for the element block.

But when I publish the page, the sub-ordered list items default to numbers. For example:

  1. Item one
    1. some test
      2 more text
  2. Item two

I have attached the HTML in this post. Since I cannot attach more than one image in a single post (new user restriction), I have attached the Live Composer preview and published page separately

Hello,

Your nested list HTML code doesn’t seem to be correct, please check this link:

Please feel free to ask any other questions that you might have.
