Maple Calculus Study Guide displays in Maple notation when it looks like it should be Typeset notation

I am using the Calculus Study Guide and the mathematical notation is half Maple notation and then half typeset notation. I have tried to tweak with Tools>Options>Display settings but it stays the same

For example:

{a[n]}[n = n[0]]^infinity;, where 
                             "a[n]"

 is the general term for the sequence, and 
                             "n[0]"

 is the starting index.
The notation is often shortened to {a[n]}; to save printing costs.

...and the math notation past the word "where" is in typeset notation but changed to Maple Notation when I cut and pasted.

Thank You in advance.
