Unquote/Cumulative project 5 in Build Basic Android apps

Obviously I shouldn’t expect the version of android studio to look exactly the same as in the lesson, but on the minor touch ups section, it says I should have colorPrimary, colorPrimaryDark and colorAccent in the colors tab. all my colors are just named for the color they are, like black or purple_200. This doesn’t seem like a version thing does it?
Also, when I run the app on a simulator or on my phone, the imageView doesn’t show up at all and the question textView moves up to the top, and I’m not sure why.
