When placing down the 2x2 dark oak sapling clusters they will not grow in most places. Turning the tick speed up does not make them grow and only certain spots in the world. Even when there is nothing above them that could block growth they still do not grow.
When placing many side by side eventually one will grow, if that tree is then destroyed nearby trees are somehow updated and will grow as well.
May be an issue with 2x2 jungle trees as well.

Yes I agree that they would not be growing with the other leaves above them but the strange part is that trees that would not have previously grown did grow after those leaves dissipated.

Oh I get what you're saying now, so they don't grow with anything above them but if leaves appear and then are broken they suddenly grow? That's a weird bug

I think that second issue you mentioned with placing many side by side is actually because dark oak trees don't grow if there are leaves above them. I can't say anything about the first issue you mentioned.
