2021.R1(S2): Cannot Delete Custom Count - Count.Api.CountController.GetcustomCountName

Description While I was working on Update UPT Factor on Custom Count, after the first Count, the item disappeared from the Custom count even though it is there in the configuration and now I can't delete this custom count that is in progress.

Envrionment = JAT
Store = 01560 Castle Rock, Entity = 875
URL = https://m.inform.jatesting.cfahome.com/#/Inventory/Count/Edit/Custom1

Steps
1. Navigate to store and URL
2. search for 'Honey, Packets'
Observe: There are no items to count
3. Delete the count with no items

Results:
System.NullReferenceException: Object reference not set to an instance of an object.
at Mx.Web.UI.Areas.Inventory.Count.Api.CountController.GetCustomCountName(CountType countType)
at Mx.Web.UI.Areas.Inventory.Count.Api.CountController.Get(CountType countType, Int64 entityId)

Expected: Count to be deleted
