contains function not giving desired results

We are trying to compare to one intake value with data that is coming from another system. Both these values are present in pv and we are using contains function inside a script task to check the same. But even though the value is present in array, its giving false. 

Array value

Single value


Both are of same data types but still giving false. contains(arrayValue, singleValue) is the function being used inside a script task. Let us know if we are doing something wrong here.
