Trouble importing from Inkscape to Synfig

Hi! I just created a Vector art in Inkscape. And I saved the file as “.sif”
And it was successful. I opened ‘.sif’.
And after a few seconds, the Synfig Studio was opened. And I can see in the layer window the respective layers.
But the problem is that I can’t see the art visible. It’s invisible and I really don’t know why.
I’m not sure if I’m wrong in my method of importing and exporting the art.
Please anyone help me through this.
For your info, I’m attatching the screenshot of my Synfig project.

you can go through all layers of your file and check the two parameters: Amount and Blend Method.

If further assistant needed, please share your file, so someone can have a look and figure it out (hopefully)
