yline(app.UIAxes_2,0, 'k_', 'LineWidth', 2);
Underscore is a marker style that indicates a horizontal line. You want
yline(app.UIAxes_2,0, 'k-', 'LineWidth', 2);

Something in your code invokes either xline() or yline(), and specifies a marker in doing so. For example,
xline(4, 'r*')
However, xline() and yline() do not permit markers.
