I’ll toss out a similar problem I had a long time ago and it was tied to the FontAwesome ICONS.
I wish I could remember what all I did but it took me a while to figure out it was like padding around the icons or something like that.
@hango That’ll do it, but if I recall correctly, if you set bottom center and top center to 20%, left and right will automatically take up the slack, no need to convert them, conversely, if you set left or right to 40%, the remaining 60% would automatically be split between them.
