No, that is a driver issue and has not been fixed yet. It occurs when we are reading the button voltage level just while it is changing. Then we read a temporary voltage that represents another button than that which was pressed.

The fix is to read the voltage twice and filter out large variations, but that adds some other complications which is the reason we haven't implemented it yet.
