API redirect 301 for pairs

what is the reason for the 301 redirect for markets:
https://matcher.wavesplatform.com/matcher/orderbook/8LQW8f7P5d5PZM7GtZEBgaqRPGSzS3DfPuiXrURJ4AJS/WAVES
https://matcher.wavesplatform.com/matcher/orderbook/WAVES/HZk1mbfuJpmxU1Fs4AX5MWLVYtctsNcg6e2C6VKqK8zk
it does not math to the priorities in https://matcher.wavesplatform.com/matcher/settings

this markets i’m got from httpps://matcher.wavesplatform.com/matcher/orderbook

These pairs correspond to the settings. That asset becomes a price that is higher in this list
