Maximum level of child queues in QT

RouterOS General
1

Hello, I tried to make nested queue tree rules up to level 7 but the traffic does not reach this level of rules. If I move the rule one level up, it is working.
It’s like: Global rule A → child B → child C → child D → child E → child F → child H → child I (this child is marked as invalid).

Is there some restriction how many child levels can exist in the queue tree?

any idea?

7, apparently. I never tried this but you found it out already.
