GIMP into Synfig

Installed Synfig and it runs fine. Installed the export plug-in for GIMP and it’s 100%. When I exported my png from GIMP into Synfig, it brought the image in with canvas size [ 1080 x 1920 ] as it should. The problem comes when I try to grab the actual image to keyframe it. It is merged to the background layer and I cannot move it properly like in the tutorial. Should I be doing something differently on the import from GIMP? thanks.

What do you mean with merged to the background layer? Does the imported gimp file has its own group or switch layer?
Can you attach the .sfg file?
