I wanted In Stock and Out of Stock options to appear in Layered Navigation.
Action: I made changes to attribute Quantity accordingly for use in layered navigation.
Result: More Information tab in Product Page disappeared, only Reviews tab remaining. ( It took a long time when I became aware about this)
Action: I reset all the options of Quantity attribute to its default value.
Result: More Information tab appeared again in the Product page.
Is there any connection between these two?
