I don’t have that particular scenery pack but it might be a case where, thanks to WU X, you need to go into the Content Manager and delete some specific parts to prevent the issue. The same thing happened with the ORBX Catalina Airport. When WU X added the Gaya-made version, they overlap poorly and give some weird terrain morphing issues. But once the new Gaya airport is removed, the ORBX one is perfect again.
