1.6.0 Frame interpolation eating frames

Win11; AMD; NVidia.

Whatever frequency I set, whatever model I set, whatever file I upload, frame interpolation eats frames and the output movie is shorter.

In TVAI 6.x all works well.

Can you share an input/output sample?

I sent this sample files:
Dark Oracle 1x01 (0-1.30m) Pilot - 1080p.x264_prot3_slp25_NE_iris2_aion1.mp4
Dark Oracle 1x01 (0-1.30m) Pilot - 1080p.x264_prot3_slp25_NE_iris2.mp4

Maybe you already know this, but I looked into this error, and it occurs when changing scenes, where it eats one frame. It only does this when scene detection is enabled.
But there is one more error when this option is enabled. At the end of 44 seconds there is a quick zoom. It adds the frames correctly, but then repeats this approximation again.
