Attributes not being received by CAS client

[McLennan, Neil R]

I am having major problems with Shibboleth outputting attributes to CAS. Some attributes are being output but some are not.
It was working fine a few weeks ago, but not sure what has changed. What might determine which attributes end up being output?

The logs show the following

Attribute filtering engine 'ShibbolethAttributeFilter': 1 values for attribute 'givenName' remained after filtering
Attribute filtering engine 'ShibbolethAttributeFilter': 1 values for attribute 'sn' remained after filtering
Attribute filtering engine 'ShibbolethAttributeFilter': 1 values for attribute 'department' remained after filtering
Attribute filtering engine 'ShibbolethAttributeFilter': 1 values for attribute 'email' remained after filtering
Attribute filtering engine 'ShibbolethAttributeFilter': 1 values for attribute 'title' remained after filtering
Attribute filtering engine 'ShibbolethAttributeFilter': 1 values for attribute 'commonName' remained after filtering
Attribute filtering engine 'ShibbolethAttributeFilter': 1 values for attribute 'eduPersonTargetedID.old' remained after filtering
Attribute filtering engine 'ShibbolethAttributeFilter': 2 values for attribute 'eduPersonAffiliation' remained after filtering
Attribute filtering engine 'ShibbolethAttributeFilter': 1 values for attribute 'eduPersonPrincipalName' remained after filtering
Attribute filtering engine 'ShibbolethAttributeFilter': 2 values for attribute 'eduPersonEntitlement' remained after filtering
Attribute filtering engine 'ShibbolethAttributeFilter': 2 values for attribute 'eduPersonScopedAffiliation' remained after filtering
Attribute filtering engine 'ShibbolethAttributeFilter': 422 values for attribute 'memberOfAll' remained after filtering

However only title, commonName , eduPersonTargetedID.old , eduPersonEntitlement, eduPersonAffiliation, eduPersonPrincipalName, memberOfAll are being received by the CAS Client even though they do not have 
The following are not being received givenName, sn, email, department, email
