Overlapping frames on an OM-body is almost always due to improper film
loading.
Do NOT put the film leader THROUGH the take-up spool. As shown in the
instruction manual, put the leader INTO but not THROUGH the spool. If
the leader protrudes through the spool, the spool will get too big, too
soon, and press back on the pressure plate, allowing the film to slip
over a sprocket tooth -- ergo, overlap. This may begin as early as 12
frames, seldom sooner, but often as late as 20 or so frames into a roll.
The only other reasonable causes are (1) gummy rewind release not
returning to vertical fully, or (2) worn out sprocket (it has teeth
inside to engage a "T"). Either of these can be reproduced without film
-- check by dragging on the sprocket with your finger as you wind the
camera. If the sprocket skips, you'll feel it.

Few off-brand lenses are worth the investment for repair -- zooms are
too much trouble and fixed lenses are too cheap to begin with.
