I've been using SPCascadeDropdowns for several years and have not had any issues...until now and it has got me puzzled.
Here's the setup:
SP 2010 Enterprise
Parent List: Requests
Child List: Request Note
Child List: Request Task
Child List: Request Task Activity
Child List: Request Issue
As expected, changing the parent dropdown triggers the cascading changes to the child dropdowns. With the exception of one parent list item (1 of 75). Even though that parent list item has verified children in two of the child lists (as seen is the last screenshot below), the child dropdowns do not filter for this one item.
I am at a loss trying to figure this problem out and any tips would be greatly appreciated.
