Changing options in IT

I recently purchased a new computer and had to download Instant Text again. Now I'm having a hard time setting up my computer the way I had it set up on my old computer. It is showing both the phrases and words, so when I try to add an "s" to the end of a word, it expands to "such." I only have my 1 glossary that I have always used, but I noticed that single10 shows under the "Includes" box on the glossary viewer. Is there a way I could set this up so that none of the single letters expand?
