Event is missing `indexed` fields

Github username: @mhhacker111 Twitter username: -- Submission hash (on-chain): 0x2eb3255080389ce406e30f96af95197fac9e0e4c819c58e7f909148a50e7575d Severity: low

Description: Description\ Index event fields make the field more quickly accessible to off-chain tools that parse events. However, note that each index field costs extra gas during emission, so it's not necessarily best to index the maximum allowed per event (three fields). Each event should use three indexed fields if there are three or more fields, and gas usage is not particularly of concern for the events in question. If there are fewer than three fields, all of the fields should be indexed.
