Description:
After upgrading to 9.5 SP1 you noticed that when you edit a template that contains "distribute software" actions, the Packages information is lost.
You need to reselect packages.
Issue:
It seems to be linked to packages
Workaround:
1- Make an export of the packages.
2- Delete tasks that were linked to these packages
3- Delete the packages
4- Imported the packages back (from step 1).
