Cannot choose Networks on ESXi 6.5 U1 via Webclient

I have configured 4 Network Interfaces (Uplink1, Uplink2, DMZ, isolated)

Some older machines have a configuration like (in .vmx) that work fine with Uplink1 or Uplink2.

ethernet0.present = "true"

ethernet0.wakeOnPcktRcv = "false"

ethernet0.networkName = "Uplink1"

ethernet0.addressType = "generated"

ethernet0.connectionType = "bridged"

ethernet0.generatedAddress = "00:0c:29:b9:5f:c6"

ethernet0.pciSlotNumber = "32"

ethernet0.generatedAddressOffset = "0"

I now try to add a new Machine, but can only assign DMZ or isolated as network adapters

ethernet0.virtualDev = "vmxnet3"

ethernet0.networkName = "DMZ"

ethernet0.uptCompatibility = "TRUE"

ethernet0.present = "TRUE"

ethernet0.generatedAddress = "00:0c:29:62:cc:e1"

ethernet0.addressType = "generated"

ethernet0.pciSlotNumber = "192"

ethernet0.generatedAddressOffset = "0"until now I have n

Webclient only shows DMZ and isolated as available adapters. If I manually edit ethernet0.networkName it does not work either.

Any ideas?
