R3D at 25fps, converted to 24fps in FCP have error in Lite v

I have a problem with the Lite version. I need to correct a draft DCP (24fps) and finish in DaVinci Lite. My original Red come to 25fps. In FCP I made a xml in 24fps. At Davinci matter in Timeline, each plane is separated from another by some frames. What is happening? Thank you!
