Burying happens as you review cards. At the start of a new day, the counts shown on the deck list are the counts before any cards have been buried. You are using the v3 scheduler, and in it, interday learning cards also contribute to the daily limit, but intraday ones do not.
If you click on Aktiv, UG’s limits will only affect cards from UG, not cards from its subdecks: V3 Scheduler: Parent/Child Review Limits and Deeply Nested Decks
