EL Expression is showing false even if binding parameters are passing

I have a requirement where we need to set as required a field when transaction class is Credit memo and BU is any of the values. But when doing the test for the EL expression it is resulting to 'false' Below is my expression

#{(bindings.TrxClass.inputValue =="Credit memo") && (bindings.BuName.inputValue=="TGBS_BU"||bindings.BuName.inputValue=="TPITIND_BU"||bindings.BuName.inputValue=="TPIND_BU"||bindings.BuName.inputValue=="SAFREL_BU")}

Am I missing something? I have attached a screenshot of the result when doing the test

Thank you
