Contents of edit boxes not kept when I submit changes

I have been trying to create a template for a CCK node type unsuccessfully. I check the "Affect body output checkbox", make my changes, and click submit. There's no error, I get the " template saved" message for whatever content type I'm working with, but after the page refreshes after hitting submit the edit box for the body now just contains " print $body " as if I've never changed it. If I then view nodes of that type it does seem that it saved my changes since they show up in the node view, but it makes tweaking it or adding to it later problematic unless I keep a text file of all the templates I've written handy to copy/paste the old contents back into that box.
