Dynamic Row Level Security model is not working after refreshing the dashboard

[kfaiyaz]

I have dynamic RLS set up in my dashboard. 
The RLS model was working fine until I refreshed the dashboard recently. 
The strange part is that RLS is working on USER_RLS_ENBDR part but not working on USER_RLS.

The set up is exactly the same.
User_RLS connected with VW_Role_Based_access using Work Email.
VW_Role_Based_Access is connected to Department_RLS using Reporting_Home_Dpt_CD
Department_RLS is connected to the values (Fact table) using department. 

In the Manage security Roles, on department_RLS I have following:

[REPORTEE_HOME_DEPT_CD] IN SELECTCOLUMNS(
	FILTER(
	'VW_ROLE_BASED_ACCESS',
	RELATED(User_RLS[WORK_EMAIL])=USERPRINCIPALNAME()
),
	"Department_RLS"
,[REPORTEE_HOME_DEPT_CD]
)

On User_RLS and on VW_ROLE_BASED_ACCESS table, I have 

[WORK_EMAIL] = USERPRINCIPALNAME()

Can anyone provide me with any suggestions or idea on how to fix this issue. Thanks

Can you provide some samples of what is in your columns exactly?
