Expected Behavior

Get Vanilla minecraft flowers when bone mealing grass blocks

If you bone meal grass blocks (tested several vanilla minecraft biomes), you only get tall grass and Wild Flax Plant.
If I disable Silent Gear and run the pack again, Poppy's, dandelions,... do spawn with bone meal

Steps to Reproduce the Problem

1. Install any of the versions above, maybe earlier versions as well
2. Bone Meal grass blocks
