Invisible mouse clicks

Hey,

Within one of my slides, I would like to show a mouse action, where the mouse starts at one point, moves downward, and shows a click action. I have achieved this by having an invisible mouse in the previous slide on the starting position, and a regular mouse in the current slide (see screenshots, with censored main viewer because of liability issues). However, when I look at the result, there is also a click action shown for the invisible mouse at the end of the previous slide (or the start of the current slide). I already set the mouse click to <None>. Is this a bug, or is there something wrong with my settings?

Cheers,

Micha
