Hi,
Reccetly I encountered a problem with my layout function. My Layout Page appeared a thick black border with no use(It doesn't appeared if I export the graph) while it's kinda disturbing when I want to check if I add another color border to my map. I am wondering if I accidentally change some setting without notice? I'm sure it's not the map border itself, which as the picture attached shows that it's already existed even before I add any map frame to the layout.
