I’m currently getting some strange bugs in the designer. I’ve tried exiting and reloading multiple times. The consistent bug is that when I go to set the left padding for any element, 75 px are automatically added to the bottom and right padding. These setting appear gray, not blue. This occurs whether the element has a class or is currently classless. It occurs when I make a new page with an unmodified body (or one given a new unaltered test class) and add an un-classed div in the body section. It does not occur when I edit the margin of body element.
Other glitches are things like settings reverting or appearing from nowhere, or taking some time before they appear in the designer and preview.
