something is wrong with backtest Datasettings.


1)I installed SQ 4.136 RC3
2) I go to Workflow Custom Projects- GBP Simple H1
3) I changed the starting and ending date for generation (1 pic startingdate)
4) I clicked a different task element "clear databanks" (2 pic , check different element)
5) I clicked back to build strategies data, and the starting and ending- dates are resettet (3 pic, go back )
