SSIS DTS Configuration File Issue

I have an SSIS package (which is already delivered to the customer, so I can't change it), but I want to switch off (disable) one of the elements. I use a dtsConfig file (XML), so I want to just send an update to that config file to switch off the element.

So, I used the Package Configurations Organizer to generate a new config file with the element switched off, and it generated the following:-

<Configuration ConfiguredType="Property" Path="PackageRun Data LoadForeach Data FileLoad Invalid Format Recs into rej_dat_format_errors.Properties[Disable]" ValueType="Boolean">
<ConfiguredValue>0</ConfiguredValue>
</Configuration>

So I copied these lines into my "production" config file and ran the package, but got the following warning message:-

Warning: 0x80012017 at ImportData: The package path referenced an object that cannot be found: "PackageRun Data LoadForeach Data FileLoad Invalid Format Recs into rej_dat_format_errors.Properties[Disable]". This occurs when an attempt is made to resolve a package path to an object that cannot be found.

Can anyone explain why? Is there some issue with having spaces in the Path name perhaps? Is there some syntax to get around it? Why did it generate a Path that is wrong?
Thanks
