Looks like the demo website still is on 1.4.0 so wasn't able to confirm if this is isolated to my install or not.
The Drop Down Page in the Layout & Blocks Manager is not populating an active link for all items in the menu. Customer, Product, checkout, category and collection are not active links.
The html generated look like this with a missing href
<a id="dppagesproductproduct" class="d2d-dropdown">Product</a>
Using the novator theme.
