only 10 of 47 custom posts are listed

Im testing the plugin and have the same issue. Only 10 of 130 posts are showing. Any ideas?

from the dox
https://displayposts.com/docs/parameters/

posts_per_page
How many posts to display.
Default: 10
Example: [display-posts posts_per_page=”5″]

and somewhere i recall -1 == unlimited…and while ppp implies pagination, that requires an extension:

There is a pagination extension for Display Posts. It works well for me.
