Sub-bullets should have different numbering to bullets in Knowledge Base articles
Numbered lists have an option to indent into a sub-bullet and sub-sub-bullet. Those second level and third level items are showing normal numbering, same as the first level items i.e.:
1. This is first level
1. This is second level
2. This is second level
1. This is the third level
2. This is first level
But obviously the second and third levels should have some other identifiers like a), b), c), or i), ii), iii). Just as it is in Microsoft Word.
I pointed this out to Support as a bug but they informed me it is treated as a feature request and is best posted as an idea!
