Fortune Does Not Work

I have a Fortune III Diamond Pickaxe in Bedrock Realms that was previously giving me larger returns but with my Fortune III Pickaxe I am getting 5 coal from 5 coal blocks, and 5 iron from 3 iron blocks. Yields of 1 per coal block and 1, 2, 2 per iron block. This is significantly less than normal for a Fortune III enchantment.
