Unbearable: Properties disappear when element is unselected

I want to love this block theme/plugin but this is so buggy it’s ruining what was originally a great experience. When selecting a container with sizing and spacing properties set, some of the values disappear. It is seemingly completely random which properties reset. It could be the margin, the height, the left padding, the right padding, etc. When switching between a container’s desktop, tablet, and mobile views, the same thing occurs. What results is a tedious process of going back and forth fixing values constantly until you get lucky and nothing changes when you select a different element.

I’ve found pressing ctrl+z will fix an element that has it’s properties reset, but this also undoes content changes or other things you’ve done.
