Virtual Server Type inaccurate when using Native SOAP call to LocalLB:VirtualServer:create

I'm using native SOAP call, LocalLB:VirtualServer:create, to create Virtual Servers. Setting the VirtualServerType to RESOURCE_TYPE_POOL results in a server that's of server type Performance(L4) in the GUI. Here's the request that I'm using. Notice that the server types are different: one is RESOURCE_TYPE_POOL, and the other is RESOURCE_TYPE_FAST_L4: ~~~~~ myTestVirtualServer10 192.168.10.20 8080 IP myTestVirtualServer11 192.168.10.21 8080 IP 255.255.255.255 255.255.255.255 RESOURCE_TYPE_POOL myTestPool2 RESOURCE_TYPE_FAST_L4 myTestPool2 PROFILE_CONTEXT_TYPE_ALL tcp PROFILE_CONTEXT_TYPE_ALL tcp ~~~~~ When I query the server type, LocalLB:VirtualServer:get_type, with the following: ~~~~~ myTestVirtualServer10 myTestVirtualServer11 ~~~~~ IControl returns the following - Notice that they are the same server type and it's RESOURCE_TYPE_POOL: ~~~~~ RESOURCE_TYPE_POOL RESOURCE_TYPE_POOL ~~~~~ In the Management GUI, both servers show a server type of Performance(L4). Anyone have an idea of what's going on here? Software is F5 LTM software appliance 11.5.
