[MapProxy] Cache with multiple grids

Dear list (dear Oliver! ;)),

I am defining a seeding task on a cache with multiple grids. Each grid is
spread a different range of zoom levels and of course over different areas.

(*) It seems that MapProxy does not create a combined set of relative zoom
levels in my cache.

In the case of 2 grids, the coverage of the grid is taken from the 2nd one
while tiles are the ones from the 1st grid since when it's time to seed the
2nd grid, MapProxy wrongly believes the tiles are already cached (probably
because the path is the same due to (*)).

Am I doing something wrong here?

Thanks for helping,
-Piero
