Double 'Proceed' button bug

I ask the agent to create an implementation plan for a given feature. The agent creates it in an .md / artifact file, which has its own ‘Proceed’ button in Antigravity, as shown in the image. The same button appears next to the message input box for the agent. I click the button next to the chat; the button disappears, and the agent proceeds with implementing the feature. However, the button displayed in the .md file does not disappear. What’s more, clicking it disrupts the agent’s operation. This shouldn’t happen. Clicking either of these buttons should remove both.
