Why do my lockscreen notifications disappear immediately after they appear

[Zach Cleave]

So everything was fine until a few days ago when I downloaded a launcher app from the store, then I ended up deleting it but from then on whenever I got notifications from Snapchat, etc. They would appear on the lockscreen but disappear once the screen shut off. All of my settings are on for notifications and app settings but it really annoys me because if I'm not looking at my phone I have no idea if I'm getting messages or not. Any help?
