Hi,
Please right click on the smart object and Arrange it to "Bring to front" and then check.
If still the reset button function then you can use the standard advance action on the button which brings the smart object that it should Show>Smart Object and Hide>Reset Button.
In order to bring the reset button back you can add another standard advance action to Hide>Smart Object and Show>Reset Button.
I hope this helps.
Thanks
Vikas
