Problem with Pre-compose

[MicTin]

My pre-composed layers are deleting last frames of layer or changing their positions after i save and close the project. It happens mostly when i enable frame blending and fps of a clip are lower than fps in comp settings.

Check the composition settings advance Tab, 

Is " preserve frame rate when nested " turned on of off?

It doesn't work, i already tried.

Have you tried turning on "Continuous Rasterization" for the precomp layer ?

[MicTin]

I just tried, doesn't work either. I think it may be because when i use pre-compose on a clip with frame blending, the fps in the pre-compose settings should be the same as the fps in the main composition settings. But for me the fps remain the same as in the source.
