Wrong button in Stage Management interface for clearing player chat

[helenvarley]

i just noticed an odd button in the Stage Management interface, that is different from all the rest and doesn't say what it does. i clicked it & got the message "Player chat cleared successfully" so it must be the "Clear Chat" button. it seems that it has somehow got the button from the chat window of the live stage.

this is on dev-app:

this is how it is on upstage.live, & how it should be:
