some error in importing data

1,Some confused setting:

We can add symbol in 'Data' or  'Instruments'  of 'Data Manager'.  But sometimes it could be invalid.  It show nothing after add symbol. And it prompt that it have that symbol when we add it again.
I like the simple setting like  that in the SQ3.8. It's more clear in SQ3.8 than that in SQ4.
2, it can't recognize the timeframe
I try many times, but beta2 can't recognize the time frame. it is always tick type.
