Replacements don't appear to work in Bloomburrow packs

**Describe the bug**
So for the Wildcard slot in the Bloomburrow editions file it says:

[Wildcard]
Base=Common:fromSheet("BLB cards")
# I don't know about these numbers, so i'm just copying them from MH3
Replace=.417F Uncommon:fromSheet("BLB cards")
Replace=.078F MythicRare:fromSheet("BLB cards")
Replace=.004F fromSheet("BLB borderless")
Replace=.042F fromSheet("BLB showcase")

But even if I change the Uncommon replacement rate to 0.900, the wildcard is ALWAYS a common.
If I change the Base card to Uncommon or RareMythic, it's then always an Uncommon or RareMythic.

Also, as shown above, the rare replacement line says "Replace=.078F MythicRare:fromSheet("BLB cards")" but should it not be RareMythic? I'm not sure because even if I change it, the same problem of always getting a common still occurs.

**To Reproduce**
Steps to reproduce the behavior:
1. Generate Sealed pools for Bloomburrow
2. No matter how many times you generate a new pool, the wildcard will always be common. This is known because there's always only exactly 6 rares/mythics, 18 uncommons, and 54 commons, which can only happen if the wildcards are only always common.

**Expected behavior**
Uncommons and Rares/Mythics, and others will appear some of the time in the wildcard slots
