getmarketsummary returns a random market

[cryptodoctor]

Whenever I call get_marketsummary(market) I do not get the requested market summary returned. Instead I get a completely random market summary.

import bittrex
from bittrex.bittrex import Bittrex, API_V2_0

my_bittrex = Bittrex(None, None, api_version=API_V2_0)  # or defaulting to v1.1 as Bittrex(None, None)

def get_price(market):
    return my_bittrex.get_marketsummary(market)

print(str(get_price('BTC-LTC')))

What gets returned is a random market summary such as:
{'success': True, 'message': '', 'result': {'MarketName': 'BTC-2GIVE', 'High': 8.4e-07, 'Low': 6.5e-07, 'Volume': 22415588.14212696, 'Last': 7.8e-07, 'BaseVolume': 16.67671564, 'TimeStamp': '2017-12-17T07:08:27.897', 'Bid': 7.8e-07, 'Ask': 8e-07, 'OpenBuyOrders': 298, 'OpenSellOrders': 1491, 'PrevDay': 7e-07, 'Created': '2016-05-16T06:44:15.287'}}
