This issue was already posted :
open workspace "my file" right click on folder of your choice for the first time menu download is displayed
right click on second folder of your choice menu download is not displayed after the menu "Download" is always hidden
the only workaround is "F5" on each folder you want download
do you already have this problem ?
after many tests I did not find anything to solve it.
thanks for any answers
