Platforms are not being applied correctly to Visual Studio projects

I'm experiencing the following issue, I have a simple script with the following code

configurations { "Release","Debug" }
platforms { "Win32", "Win64" }

filter "platforms:Win32"
	architecture "x86"

filter "platforms:Win64"
	architecture "x86_64"

project "testproject"
	
	kind "StaticLib"
	language "C"
	includedirs { "../../deps/include" }
	files { "../../deps/src/*.c" }
	
	filter {"configurations:Debug"}
		defines { "_DEBUG" }
		symbols "On"
		targetname "depsd"
	
	filter {"configurations:Release"}
		defines { "NDEBUG" }
		flags { "MultiProcessorCompile" }
		optimize "Speed"
		targetname "deps"

The problem is that after generating the Visual Studio 2015 files, I can see that the target platforms have been created at the solution level, but not at the project level, I mean, the solution does have the Win32 and Win64 platforms, but the project doesn't.
I've also tried to redeclare the platforms inside the project, but still doesn't work.

Am I doing something wrong?
Thanks in advance!!

Reproduce the report by generating Visual Studio 2015 files from the shown Premake script, then compare the solution-level and project-level platform entries. Trace the Visual Studio generator's platform handling and confirm that Win32 and Win64 are emitted for the project as well as the solution.
