Replacement 42mm Screen doesn't fit

I purchased a replacement screen from iFixit and followed the replacement steps. Now when I am putting everything back together the screen doesn't want to fit back on. It sits flush all of the way around except fro the top. When I look at the side that is not closing properly I see two little tabs that don't appear to be on my old screen. Now I am not sure if they were at some point part of the original screen since the screen was broken and came off of the watch in pieces. Here is a picture that will hopefully help show what I am talking about.

Thanks

Here is another picture. It shows the side where the clips should clip into.

After resetting the watch and repairing it, it appears to work properly but I still can't get the screen to sit flush.
