In my new router there is Parental Control option.

There is an option to create multiple profiles..

I created one profile with some internet restriction from 2PM to 4 PM for my kid and added his device to it.

Then I created second profile with internet restriction from 7AM to 12PM.

I wante3d to add the same device to the second profile to have another time period restriction.

The device was added to the second profile but it was removed from the first one.

I am unable to make multiple time restrictions for one device for one day. 

So, whenever I made changes on the time and added it on the different profile, It took the device data and emptied out the other profile

I think TP-link technical support should take into consideration this malfunction and update the software.
