SSIS seems to be discarding columns

$

I have a simple SSIS package with one data flow step that has several lookups...

... Flat File Source (.csv)

... Conditional Split (discards a spurious row or two)

... Sort (no good reason, just liked to see the rows in order)

... Lookup 1 (Matches work order numbers [non-numeric] and adds two new columns)

... Lookup 2 (Matches the PO Number to the Master [non-numeric] and adds one new column)

--- Here is where the data preview shows I've lost all the columns that weren't added by Lookup 1 and 2!

... Lookup 3 (Matches the Vendor Name (I know....) to add VendorID Column) -- shows up in preview

This was working until I added the sort...what'd I do?

Alright, I figured out that somehow I removed those columns from the Data Viewer, whose properties show up when you double click the data viewer icon. I think it's because they were active when I inserted the sort, so for a brief moment, all those columns disappeared.
