How to make ores generate in the nether in 1.11.2

I'm having problem with the nether ore generation.. I made my ore extremely common to generate in the nether but I wasn't able to find it anywhere, I'm using MCreator 1.7.5 (1.11.2)

This was also a problem in 1.7.10 modding, didn't it get fixed?

Here is the code for the block if needed..
