numberposts isn't working

When using this code:
[catlist id=49 orderby=title order=asc numberposts=-1 ]
at this domain:
http://eatwellenjoylife.com/main-dishes/

I can’t seem to get all of the posts in the category to display. There are 49 posts in this category, but only 10 show. I tried changing the settings in the reading section of the dashboard. I even set it to 100, but only 10 show up.

I have a feeling it’s because of the pagination in the template, but I’m not sure.

any help would be greatly appreciated.
