Many thanks to all (especially Günter and Helge) for helping me solve this issue of having different counters throughout a document. This has also helped me understand how LyX behaviour has be coded to mirror the desired LaTeX behaviour, and how the LyX modules design is so useful for this.
Perhaps we need a bit more documentation on how to use modules to set-up specific behaviours in both LyX and LaTeX. Cheers. Mateo.
