Why the data tick download start from is different in 2 same broker terminal?

 

Dear experienced traders, 


Do you know why the data tick download start from is different in 2 same broker terminal? 

I download all ticks both from 1970, but one download data from 2019, the other one from 2017. 

I tried both for several times. 


Thank you in advance and best wishes,

Sky



 

This issue seems because of terminal update.
