Rank Tile Not Grouping, Needs Case Sensitive box


I am using the Rank tile, ordering on a Timestamp and the column that makes up a partition is Customer. For example, I have "CUSTOMER A" and "Customer A." These are in the raw data and represent different clients, but the Rank is treating them as the same. I will probably value map one of variations to be unique, and I'll have to repeat the process for any other Customers with a similar issue. This could be solved with a Case Sensitive check box in the partition section.
