web3.py query for Uniswap V3 Factory contract events on Arbitrum, getting all pools created since block 0, but it's missing multiple token pairs

Question

I'm using web3.py to parse through all liquidity pools created since block 0 on Uniswap V3 Arbitrum. Atm, about 486 different pools a returned, but none of them are pool I'm expecting. Is there some other reason why the pools might not be showing up? These two tokens are not found: Ramses (0xaaa6c1e32c55a7bfa8066a6fae9b42650f262418) and PLX (0xc8ccbd97b96834b976c995a67bf46e5754e2c48e). They both have token pools on v3 Uniswao Arbitrum.

infura_url = "https://{arbitrum-mainnet.infura.io/INFURA_ID"
web3 = Web3(Web3.HTTPProvider(RPC_URL))

# Uniswap V3 Factory contract
contract = web3.eth.contract("0x1F98431c8aD98523631AE4a59f267346ea31F984", ABI)

pools = contract.events["PoolCreated"]().getLogs(fromBlock=from_block, toBlock=to_block).get_all_entries()

for each in pools:
    # Search pools for PLX token
    if each["token0"].lower() == "0xc8ccbd97b96834b976c995a67bf46e5754e2c48e" or each["token1"].lower() == "0xc8ccbd97b96834b976c995a67bf46e5754e2c48e"\
                == "":
        # Expecting PLX/WETH pool (0x7e48e98c9841bdd965986d2a4b37457938b27ee3)
        # But returns nothing instead
        print(each["pool")
        break
