English Localization issues with Leshen during Special Assignment

[jtmal0723]

Unfortunately, another issue has arised with the en-US.json localization. This time it has to do with the Leshen monster that is fought during the Master Rank Special Assignment "Contract: Trouble in the Ancient Forest". I am unsure which parts these are, I'll have to do more testing when I can. I just wanted to make a note for when I do my research, unless someone beats me to it! Keep up the good work!
