I put a deck to a parent deck then all of a sudden, the new cards of that deck won't appear

I tried putting a specific deck to a parent deck but whenever I’m putting it to the parent deck, the new cards won’t appear. Then when I remove it from the parent deck, the new cards are visible. Can someone help me with this? Thanks!

Here are some references for example:

Show the deck options.
Do you have the “Limits start from top” setting enabled?

[daikinftx]

Yes it is enabled
