sus using chart speed changing doesn't export collectly

[Oomisokadesu]

I made this chart.
I saved it by .mmws and exported it by .sus .
.mmws chart can be inported collectly, but .sus chart can't collectly like this.

I tested this sus but timings sped up or down aren't right so I guess not .sus importing system but exporting doesn't work.
I think using BPM, tempo and speeding at same time cause bug.
(I use win.10 , MMW v2.2.0)
