Some objects wrongly added and some objects missing when importing an svg

Hi, everyone. I have tried to upload a work-in-progress model from Inkscape to Synfig to test whether it can be animated and have found that, upon importing the svg file into Synfig, several objects have been added, several have disappeared and all the clones are missing. Any idea what might be going wrong? Why are the pupils missing on the models, and can clones not be imported into Synfig at all?

Here are two screenshots showing the situation, in Inkscape and Synfig, uploaded onto imgur. Note that the models shown in the images are nude human characters.
