You surely don't have to move files manually, and the FSDT_KORD_SF01.bgl should NOT be placed in the scenery folder. It's a file that comes with two different versions, one for P3D4 and a different one for P3D5, and it's referenced in the add-on.xml of both sims, each one pointing to its own variant so, for example, the last lines of add-on.xml for the P3DV4 version will look like this:
<AddOn.Component>
<Name>FsDreamTeam Chicago O'Hare V2 Additional Compatibility Layer</Name>
<Category>Scenery</Category>
<Path>C:\Program Files (x86)\Addon Manager\FsDreamTeam\KORDV2\prepar3dv4\Scenery</Path>
</AddOn.Component>
and the last lines of add-on.xml for the P3DV5 version will look like this:
<AddOn.Component>
<Name>FsDreamTeam Chicago O'Hare V2 Additional Compatibility Layer</Name>
<Category>Scenery</Category>
<Path>C:\Program Files (x86)\Addon Manager\FsDreamTeam\KORDV2\prepar3dv5\Scenery</Path>
</AddOn.Component>
The add-on.xml file is created by the installer, and changes happened when P3DV5 came out. Of course, users installing in V5 surely had to run the installer but, if you only used the *updater* to update the scenery for P3D V4, and never reinstalled it since the V5 version ( which introduced two variant of that file ), you will be missing those lines, since the updater doesn't add them automatically.
So, either add the lines to the add-on.xml manually ( using YOUR path, of course, these above here are just examples using the default installation path ) or reinstall KORD using the full installer, which will create all the correct add-on.xml files.
