[*]When i open Ofnuts xcf file, this last step where it says "Make that new layer invisible". 
I made ring layer invisible, then ran the 'ofn-interleave-layers'. It created a new image file. That exported all the visible layers to the other page, except the grey ring layer that has the 20px circle. 
I tried exporting it to gif, all i get is the tick marker animating without the grey background.

Then, I tried making the RING layer visible, and ran the 'ofn-interleave-layers', I get the tick marker animating without the grey background, and the last frame is the grey background by itself.

I think i am missing is the copy/merge to the other layers. I am not sure what he meant by that. Does he meant I have to duplicate the grey ring layers 12 times (since I have 12 blue markets), and then merge each of these marker with the grey ring?

Thanks for patience everyone.
