Strategy autosave not work on custom projects

When we build strategies through SQ4 builder, generated strategies are automatically saved on  
[SQ4 Folder]\user\projects\Builder\databanks\Results

but when I build within custom project,
generated strategies are not saved. I looked here : 
[SQ4 Folder]\user\projects\[Custom Project Name]\databanks\Results

I started my custom project until I got 500 strategies, but no strategies are saved there.

after that, I retest all those 500 strategies and saved it into another databank named "AfterRetest"
but I can find just one strategy here :
[SQ4 Folder]\user\projects\[Custom Project Name]\databanks\AfterRetest

After all those procedure, (during I sleep) my SQ4 got blacked out so I restarted it.
but All I can found was just one single strategy.

Please check this.
