document exhibiting the problem

If you:

1. Use the 'Condition' tab of a paragraph style, like 'Body Text', to set different styles to the list level contexts (i.e. '1st List Level', '2nd List Level', '3rd List Level', '4th List Level', etc).
2. Create a multi-level list in your document.
3. Select the list and change its paragraph style to the style from step 1.
4. Save.
5. Close.
6. Reopen.

Then after step 3 all the conditional formatting will look correct, but after step 6, none of the conditional formatting will be applied.

I'm attaching a document that exhibits the situation for me and screenshots of the document before and after closing and reopening. And a screenshot of the Condition tab that shows the paragraph styles applied to the various level contexts.
