Content missing when cooking on console or PC

Hi, I am trying to cook a version (Dev and Shipping) and I seem to be always missing some staticmeshactors in the map.I tryed looking in the log file and there is no error/warning messages.

(Edited)
I discovered that it was due to streaming. I’m trying always loaded maps or loading with blueprint and both are not working. Stat levels show that the levels are loaded and visible (Red) , but they do not show as such.

any ideas?
