I'm having trouble funding accounts when starting parity with a custom chain. My json file is

I start my local parity node with parity --chain parity-dev.json --unsafe-expose --jsonrpc-cors="all". However, whenever I connect to parity with metamask none of the accounts (0x1f9945a4DBe3851beDc787434d2A63dd44303f77, 0x68Ff636CA053Adb00804923ef1e23bA729760cf6 and 0x14fE6Fc199DdaB2b94b8d4bf8664c86a4d275711) have any balance shown. Similarly, when I open the parity UI and check the wallet, I don't see any accounts:
Here's what I see on metamask for one of the accounts which should have a balance. 
Here's what I see in the parity ui wallet (note PARITY-DEV.JSON in the top right):
