New map viewer showing point symbols in legend for line layer

[wayfaringrob]

Recently updated my symbology for transit lines from Classic Symbols > Basic Shapes > Basic Line to Vector Symbols > Transportation > Highway. Looks great on the map, but now my legend just shows my routes as points, in which color is difficult to distinguish. Here's a before and after:

Am I missing a setting? Is this a bug? If I uncheck "adjust width automatically," they look fine in the legend, but that's not what I want. It's also not even retaining that checkmark in the box when I click Save.

looking into this now  thanks for reporting.

This isn't a regression from the release and looks to be a bug in the API. If you want to have a ticket to track I would recommend logging a support ticket.
