Unchecked box for "Included in Drafts"[BUG LOGGED]

I unchecked the “Included in Drafts” box in all the documents in the Research folder, and saved the project, but after quitting Scrivener and opening it again, I found that box is checked again.

Same thing happened to me.

Specs:
AMD Athlon™ Dual-Core Processor
3 GB RAM
Windows Vista
