Parental Controls Issue with extender AX1800/RAX10

I have an AX1800 RAX10 with parental controls turned on. I have a child profile and an adult profile. When the devices connect directly to the AX1800 the controls work great. I also have an older wifi extender (Netgear EX7300). When any of the devices connect to the wifi network through the extender, the parental controls no longer work. I have added the extender to the child profile, but then when the adults are also connected to it, they get them more restricted controls and our screen time counts as theirs. 

Is there a way to use the EX7300 and have the devices connected to it show up on the AX1800? Or, will this take a newer extender like the AX1600 to do what we need?

Thanks!
