I can reproduce this. Just create a file .dir-locals.el somewhere with
content like this:

    ((nil . ((mode . auto-fill)
             (mode . outline-minor))))

When files in that directory are opened only the last mode
(outline-minor) in the alist is turned on.

A side note: It seems that directory local variables feature is still in
a half-finished shape:
