Secure Page Entry by EL Expression

Hi,

We've created a role on production: XX_BI_500_FINANCE and it has role category "BI - Abstract Roles".

We assigned this role to several users and ran the LDAP sync processes.
Now we are going through sandbox > Structures to create a new page entry. For the 'Show on Springboard', we want to use the following EL Expression:
#{(securityContext.userInRole['XX_BI_500_FINANCE'])}

However, I'm doing this with a user who has this role, but upon 'Validate', it keeps saying 'false'.
I've tested with other roles (Common, Procurement, Financial role categories) and this works perfectly fine.
