Failed to Add custom timeframe

Timeframe setting is very good in beta version.
But it would  fail when I add new timeframe. I can't choose minutes, hours, or some others next time.
And no errors info about this in  log file.
And The One important thing is that SQ can't run test, or generating normally. It could not start mostly!!!
There are some error info in log.
