I am currently working on a wireframing project, and I believe I may have selected an option, but I can’t figure out which one. I would like to remove the corners from each of my elements, as shown in the image.
If someone could also explain what this option is, I would appreciate your responses in advance.
This looks like you have absolute positioning turned on for these component instances. Try selecting them and look over to the frame options panel … in the top right of the panel is the absolute position toggle that has the same corners on the button. Though switching off absolute positioning will mean that your objects will then follow the auto layout rules set up for their parent frame.
