slide in plugin not working properly

I have the slidein plugin set to show up after 5 seconds. That works fine, but when you click on another page or scroll down the page or do any action, the slide reappears, even though I have it set to not appear.

I have update the newest version, which I notice has an "injection" box. Is there something else I can try in this box.

I think the slider in looks great, but need to get it to work with the settings.
