I don’t know how to explain, I’m a beginner, I was working on the design of my models to make a high-fidelity prototype, for a course project, I was editing texts and when I deleted a word and hit enter, I don’t know, it completely changed the aspect of my designs. They are just like page outlines, lines of frames and black and white texts. I don’t know how to go back to my designs with photos, texts and color.
