G3100 Router, Parental Control

[NYLife75]

Weird issue, when setting up parental control, and clicking saves or adding or removing a device from parental control, the router will kind of pause for like 20 seconds and all other devices lose internet connection. this also happens when going to the network and list of all the devices and picking a device and selecting block internet. such a simple function seems like some form of firmware bug or something. router otherwise functions normally with no issues, but trying to control kid's devices and it becomes useless.

Does the device name you selected contain space bars in them?
