[edit] Now the issue has been fixed, thanks to joe7575. As a suggestion I would say that it might be a good idea to add this solution in the help documentation.
The solution is: change the line:
local PROBABILITY_FACTOR = tonumber(minetest.settings:get("gravelsieve_probability_factor")) or 3
to:
local PROBABILITY_FACTOR = tonumber(minetest.settings:get("gravelsieve_probability_factor")) or 20
[old review]
Everything in this mod works good and as expected, but the gravel sieve (says it eleviates mining so much) actuall makes your ore drop rates become about 10-20x more rare and you end up having to mine anyway just to get baseline number of ores.

Other than that everything else works fine.
That was the brutal way to change this. Actually, it should also work the standard way.

I don't know why that didn't work for you
