well firstly the most direct is, well, like lephyr said, it says that these "sub spaces" do not have any space or time, which is contradicted since the Room of spirit and time clearly does yet it is said to be one of those "sub spaces", also the contradiction in on itself on the scan,
"どの世界にも属さない
〈亜空間〉
That which doesn't belong to the world
〈Subspace〉
この他、【図1】の世界のどこにも属さない「亜空間」が存在している。
Also, there are subspaces that don't belong anywhere in the world depicted in [Fig.1]." basically it is saying that the so called "sub spaces" do belong/aren't part of the macrocosm at all, yet here: "
そこでは「時間」や「空間」といった概念がなく、どのエリアからも切り離された次元の間に位置している。
There isn't a concept of Time or Space there, they are located between dimensions and detached from any area."it is said to be between dimensions, so if it is interpreted as being between the macrocosm dimensions, then this is contradictory to what it said earlier, it could also be interpreted as not talking about the dimensions of the macrocosm tho, that would coroborate with what it says earlier about them not being part of the macrocosm
