Commented Issue: Missing Update level rules when Revise... [295]

I have a problem when add more than 4 update level rules using Update Creation Wizard. All looks fine when press Next > Revise, but when i open again the same package, five and next update rules are missing.
Comments: Fix a typo that prevent WPP to recognise a «File Exist Prepend Reg SZ» rule when revising an update.
