To hide "Me" tab in the Spring board based on Custome roles for Suppliers

Summary:

Hi Team,
I also tried through Cutom roles, regarding one of the tab "Me" need to hide from spring board based on the custome roles, but it does not work. The requirement is should not visible for Supplier users, Only visible 'Me' tab for custome roles (TPG Employee , TPG Contingent Worker). But does not work. Please refer my EL expression source code. Validated the Code It is showing as value "False", But does not work with this code. What could be the reason?

EL Expression source code:

#{(securityContext.userInRole['TPG Employee'] || securityContext.userInRole['TPG Contingent Worker'] || securityContext.userInRole['TPG Line Manager']) && ! (securityContext.userInRole['Supplier Administrator'] || securityContext.userInRole['Supplier Self Service Administrator'] || securityContext.userInRole['Supplier Sales Representative'] || securityContext.userInRole['Supplier Accounts Receivable Specialist'] || securityContext.userInRole['Supplier Bidder'] || securityContext.userInRole['Supplier Product Administrator'] || securityContext.userInRole['Supplier Contract Administrator'])}
