How do you disable pizzicato?

I'm having a curious problem: I used pizzicato in a certain section, and now those staves seem to be "stuck" in pizzicato mode. Everything after the pizzicato section is still playing pizzicato on those staves, and I can't figure out how to turn it off.
No doubt there is some simple fix for this, but so far I haven't found it. I would appreciate some help, thanks!
