There are ED4 settings included in the Search for Settings toolbar that need to be removed.

For example, type in "toolbar" and select "Display Toolbar" and it will go to the Layout page, but the Toolbar is no longer part of ED5 itself, as it is now the standalone SI Toolbar.

I'm sure there are more settings like this that have no "destination" in ED5, so please make sure this all syncs.

Thanks
