We have enabled 'Override Daily Duration' feature for one of the Absence Plan type   > Display Features > Date and Duration

But when we are trying to add a new absence for the absence type  from  Absence Records page through  Administrator login , 
The 'Advanced Mode' option is not appearing nor Edit Entries option , instead it is showing a static text as Basic Mode and even though added absence start time 
absence end time more than 8 hours( start time : 8:00 AM  , End Time : 6:00 PM)  , the absence duration still shows as 8 hours(might be pulling from work schedule hours).
