Sorry for the delay in responding, I got pulled into another project for a bit. We've removed the sidebar from the project for the time being, but I'm seeing the same thing using the Messages
component. Where it should show the "Info" icon, it is showing the word "info". You can also see in the screenshot below, that the messages bar is also showing the word "close" instead of the close icon off to the right.
