Child deck spawning more reviews than it is set to spawn

I have a deck that has over 5000 cards, but I would like to review no more than 1 card per day. I have assigned it to a Deck options group that is set to 1 in the Maximum reviews/day setting. However, I now want to keep that review pace for this deck, but add it as a child deck to a parent deck. The parent deck has a faster review rate and uses a different options group.

One would think that simply adding this child deck with its slower review settings to the parent deck with above settings would be sufficient. However, when I add the child deck, I get many, many reviews spawned instead of the 1 that it is set to.

Does anyone know how to solve this issue?

It sounds like the v3 scheduler will do what you want.
