final cut drop zone error

Hola amigos. Tengo un problema con la "zona de caída" del inspector de video en FCPX. Al aplicar un efecto a mi clip, un efecto que consiste en enfocar solo una parte del clip y el resto tenerlo desenfocado, ya que sucede que al aplicar un corte en el clip, el video que inserté en la "zona de soltar ", en el inspector de vídeo, no estoy sincronizado automáticamente con el clip original. ¿Alguien sabe por qué el video en la "zona de caída" no está sincronizado con el clip original? Espero sus respuestas. Gracias. Adjunto algunas imágenes.

Hello friends. I have a problem with the "drop zone" of the video inspector in FCPX. When applying an effect to my clip, an effect that consists of focusing only a part of the clip and the rest to have it out of focus, as it happens that when applying a cut on the clip, the video that I inserted in the "drop zone ", in the video inspector, I am not automatically synchronized with the original clip. Does anyone know why the video in the "drop zone" is not synchronized with the original clip? I look forward to your answers. Thank you. Attached are some images.
