Shimeji Help?

EDIT
Added a download link!

Is there anyone that has this problem with their Shimejis?
They disappear behind the task bar sometimes and I can't see their legs...
The girl (with the green hair) is sitting and the boy (with the white hair) is standing.
These are the only 2 that I actually have these problems with...

Kido (girl) by [link]
Konoha (boy) by [link]
