I have a Maker DAO Vault with renBTC as collateral which shows up in zapper as "DAI / ETH". It is looking up the proper number of units but with it showing as a wrong asset it has completely wrong valuation.
I imagine this is due to a misconfiguration of the token lookup.
renBTC = 0xeb4c2781e4eba804ce9a9803c67d0893436bb27d
