Changes to a schedule object are not saved entirely when using filtered view.
Here's how to reproduce the issue:
# create schedule with 3 or more different objects - save and close
# open schedule
# open filter and define filter that results in finding 1 object, untick active option and save it (do not close schedule)
# search for another object untick active option and save it (window will reload like in save process but you can see that active option is activated again)
# close schedule
# open schedule and you can see that only 1 (first) change was made.
A bug in the AWI is causing this issue.
The bug will be fixed with a future Service Pack for Automic Web Interface.
