Object states button disappears after click
In a multi-state object, the button that activates the MSO disappears after being clicked. No where in the settings have I told it to disappear after being clicked.
Version: I'm running InDesign 16.3.2 (though I downgraded to 16.2 and am still having the problem)
Steps to reproduce issue:
I created the MSO using buttons/forms and the object states panel. Close button should revert back to original state (star).
Expected Result: Button should reappear.
Actual Result: Button is gone after click.
Video of ePub preview attached.
The problem is both in the ePub preview and when published online.
