Possible channels from cpe

so i have two routers: D-Link and TP-Link and they share a common parameter:
InternetGatewayDevice.LANDevice.1.WLANConfiguration.1.PossibleChannels

so for D-link router i get the value for this param as:

InternetGatewayDevice.LANDevice.1.WLANConfiguration.1.PossibleChannels:
1,2,3,4,5,6,7,8,9,10,11,12,13

InternetGatewayDevice.LANDevice.1.WLANConfiguration.7.PossibleChannels:
36,40,44,48,52,56,60,64,100,104,108,112,132,136,140,149,153,157,161,165

But for tp;ink i am getting like this:
InternetGatewayDevice.LANDevice.1.WLANConfiguration.1.PossibleChannels:
1-13

InternetGatewayDevice.LANDevice.1.WLANConfiguration.2.PossibleChannels:
100-140

And when i checked the router ui of TP-Link:
i saw only 3 channels supported in the second ssid i.e. in InternetGatewayDevice.LANDevice.1.WLANConfiguration.2.PossibleChannels

this is available in the router ui:
Can someone help me solve this issue?

Inform TP-Link they are violating the spec. This is the only way I’ve gotten vendors to fix their stuff.
