Upon using the command /give @p minecraft:double_stone_slab you get an error that states that minecraft:double_stone_slab is not a valid block. But, you can /setblock the double_stone_slab.
I also am curious as to the fact that when a stone stab is placed on another you get the seamless variant rather than the non-seamless variant.

Please put only one bug report in each ticket. It is very difficult to keep track of bugs when they are not in their own tickets, and it is easier for you to make multiple tickets than for the mods to separate them.
And please use the search function in the future as all of the issues are reported multiple times.
Dupe of MC-57793 (WAI) and MC-60035 (Fixed for a future version).
