iPadOS 13 Dark Mode

I was testing out the new dark mode on my iPad and our app doesn't seem to show up correctly even though we have everything set up as default settings. For example, our background is normally white with black textlabels but in the dark theme it shows the same white background with white textlabels. Another example is that our textfields went from a white background to black and the text stayed black. Is this something that we will have to change or is this a bug that will have to be fixed?
