? on Eurodam Deck Plan

[Northshorecruisers]

I was just drooling over the deck plans for the Eurodam and saw something I hadn't noticed before.
On the Navigation deck, aft - SB8162 & VA8160 as well as SB8173 & VA8171 appear to have a connecting door. But, the connected symbol is not used.
Does anyone know if these are connecting cabins?

The connecting symbol + is used between SB8162 and VA8160.
