Issues when renaming files

I'm trying to rename a file from tradinghistory/settlementReports/2013/20130327 Report_Statement (1).csv to tradinghistory/settlementReports/2013/20130327 Report_Statement.csv. When I do this via the move command, it moves it to tradinghistory/history/settlementReports/2013/20130327 Report_Statement.csv - i.e. it adds an extraneous "history" directory in the target. If I rename source files from within IntelliJ, this works, but the same issue happens within SourceTree. Thanks

See question: https://answers.atlassian.com/questions/182823/renaming-a-file-doesn-t-work

I've also attached files which show the issue (on a different file).
