Blackmagic Interlaced Video Input

We are trying to use this plugin with 1080i50 video input. But, the input frame in Media Texture has only half of HD height (1920x540).
Is there a way to receive a full frame in the interlaced mode? Or the is a way to deinterlace video in Unreal?
Thanks!

We have the same problem and anybody have the correct answer. May be is a bug or its intrinsic problem of interlaced signals.
