Thanks in advance for help

There are several possible issues. The first on that comes to mind is
the door movement. Try disconnecting it, and moving it by hand. It
should
open and close easily with the tendency to stay fully open, fully closed
with no sticky spots between.

If the reflector or the lamp are mounted on the track, the track may
be
twisting as the door moves and that could cause a misalignment.

good suggestions

in addition the door could be binding up a little at the area that it
reverses. If your closer has an adjustment for force maybe crank it up a bit
to get by the area.
