HUGE bugs

I downloaded this plugin a few days back, to use with the Jupiter theme. First I thought it was genius: simple, easy-to-use, allowing me to focus on the key issues…
Then I started noticing a couple of bugs: it changes the page settings, and messes up the layout. For instance, it changed the “sticky template” option back to default (no), modified the pages title settings… Then, even worse: it changed the page URL! I didn’t even know this was possible ! One of my main page title got changed to something entirely different, messing up my menu. My visitors got a 404 when trying to access the page.
Of course I disabled the plugin right away. I don’t know what’s going on, if it’s just an issue with Jupiter, but guys! You need to look into this.
