File Verifier tab column header

[SwissKnife64]

The "File Verifier" tab column header has unexpected behaviour.

When I move a column during width adjustment to the right margin, all column to the right of adjustment disappear. The visibility can still be toggled in the context menu, but the columns are gone.
There is no option in the context menu to add the column again.

Work around: get a fresh "File Verifier"

column should not be able to be reordered.  I will fix that
