Hi  @Myknock 

Welcome to the community.

Are any of the kids' devices using randomly generated MAC addresses?

If so, this could explain why they appear as new, separate entries in the client list every time they connect.

Some devices, especially newer ones, automatically change their MAC address at regular intervals.

MAC addresses are often used to identify and block access to certain devices. However, if a device uses randomized MAC addresses, its previous MAC addresses might still be listed in the Block List, even though the device is currently using a different one.

As these devices keep changing their MAC addresses, more and more spots in the Block List will be taken up, leading to the issue you're seeing.

The first thing I would suggest is checking the settings on your kids' devices to see if any of them are configured to use randomized MAC addresses.

Additionally, I recommend verifying how many Block List rules are currently active and whether devices using randomized MAC addresses occupy numerous entries.
