Instead of just right clicking on SSMS , these are some alternatives to locating SQL Server Collation information I use.

--To find all collations available 
SELECT * FROM fn_helpcollations()

--To find the SQL Server Collation level 
select SERVERPROPERTY('collation')

--To find the database collation level 
SELECT DATABASEPROPERTYEX('MyDatabase', 'Collation') as DB_SQLCollation;
