Published storyline scene changes when put into rise

Hi,

Ive created a storyline scene and published it to put into a rise block. However, some of the elements within the scenes (shapes) have moved when published. They are still in the correct place in storyline... very frustrating as i don't know how I can correct it.

This is a screen shot of the storyline instance:

and this is it in Rise:

You can see that the orange triangle have skewed making the gaps out of line. Anyone got any idea why this is happening and what I can do. Just looks like i'm doing a shoddy job when my alignments are out of whack.

Thanks in advance!
