To match conventions used by IR and MI, raw ores should be tagged as c:raw_xxx_ores, and raw ore blocks should be tagged as c:raw_xxx_blocks. For example, c:raw_tin_ores and c:raw_tin_blocks.

MI generates them dynamically so you won't find them in the jar but they exist. ^^

IR needs to tag them as well. This allows the unification script to detect them and hide extra variants.

I haven't found any "c" tags in MI.
There are no c:raw_xxx_blocks in IR. Also I do not see usage for it with only block <-> 9 items recipe for crafting table.
