The same risk measure can have a qualitatively different financial meaning, depending on whether or not it is applied to a volatility product.
The Volatility Products tab collects these products separately from their underlyings. The Delta measured on this tab represents a risk commensurate to Vega on the Equity tab.
The risk measures (Greeks) shown for volatility products are the same as those for equity products. However, it is important to understand that their financial meaning can be quite different.
