I'm having an issue with Greek letters in Jupyter Markdown. Ideas on a fix?

I am doing some work in Jupyter Notebook which necessitates Greek letters. (\mu, \sigma, etc.). In code cells the \mu followed by TAB works fine. In a markdown cell I expect either the lower or uppercase Greek letter, but when I hit TAB, the entire string of text shifts to the right as in a typical word processor. This is new behavior. I'd like to fix this.

print('α psyho disco β') - #This works in a code cell. 

\alpha psycho disco \beta -#This doesn't work in a markdown cell

Thanks for any assistance.
