Bug: 'Show system messages' checkbox is not rendering

[Daniel-Warner-X]

In the session chat, when a user clicks on the gear icon, a popover menu displays 'show system messages'. There is a checkbox, but it is invisible.

just next to that, there were commands and agents buttons, but they're gone now. I have also seen in the sessions list, the icon under the Action column could be a square. i dont think thats intended
