R Markdown Bullet List with multiple levels

Question

https://github.com/rstudio/cheatsheets/raw/master/rmarkdown-2.0.pdf

The above cheat list provides the following syntax for creating a bulleted list in R Markdown. *is the main solid bullet. +- secondary hollow bullet. And -- a tertiary solid square.

* unordered list + sub-item 1 + sub-item 2 - sub-sub-item 1

After outputting output using knitr, I do not get the expected result. I get what is shown below. The second and third lines are indented. Only the very last line has indents and only one indent instead of the expected two. And all bullets are a minor hollow style. It is as if I introduced the following syntax in R Studio, but I did not.

+ unordered list + sub-item 1 + sub-item 2 + sub-sub-item 1

How do I get what I intended, the first piece of inserted syntax?
