Do you see the same thing if you start Emacs using `emacs -Q'
(no init file)?  If so, it sounds like a bug
(`M-x report-emacs-bug').

Do you perhaps use library `dired-details+.el'? If so, and if
option `dired-details-propagate-flag' has its default value
of `t', and if you happen to use `(` in Dired (to toggle
showing details), then that the resulting state is used from
then on (until you hit `(` again), by default.

IOW, that could explain what you think you see.  If you did
hit `(` then what you get from that (e.g. showing details)
will be what you see in Dired from then on (until you toggle
with `(` again).  If you don't want such propagation then
customize the option value to `nil'.
