Answer 1

There could be some activities of this item type which might not be END-DATED.
Please run below sql and check. You need to end_dated the previous ALL activities, EXCPET LAST ONE WHICH LOADER will end date.
select PROTECT_LEVEL, CUSTOM_LEVEL, VERSION, BEGIN_DATE, END_DATE
from WF_ACTIVITIES_VL
where ITEM_TYPE = 'EMS'
and NAME = 'NTF_MGR_ACTION_TAKEN'
and sysdate >= BEGIN_DATE
and sysdate < nvl(END_DATE, sysdate+1);
