Background
I'm working on a story map where I've been setting up several sidecar sections in the story map builder. I have web maps set up as my main content, and I notice in the legend that I haven't renamed my layers, so that my legend is not giving user friendly labels for my features. OK, so the solution is to go back to my web map, change the layer names, and save the map.
The Problem
The issue I'm having is that, after saving the map and reopening the story map builder, I'm not seeing my saved changes in the legend. The builder is remembering the state of my web map - specifically the legend - as it was before I saved the map. I can work around the issue by creating a whole new sidecar slide; when I add the map to the new sidecar slide it comes in with the correct legend. But obviously this workaround is less than ideal because it requires that I replicate the work that I've already done.
Is this an expected behavior or a bug?
