qmake generates an error file from .pro to .vcxproj

set TRANSLATIONS and CONFIG +=  lrelease embed_translations at the same time in the .pro file.

then qmake -t vcapp xxxx.pro

the generated .vcxproj.filter is error. 

content:

<ItemGroup>
 <CustomBuild Include="..\xxx.ts">
 <Filter>Translation Files</Filter>
 </CustomBuild>
 </ItemGroup>
...
 <ItemGroup>
 <CustomBuild Include="..\xxx.ts">
 <Filter>lrelease</Filter>
 </CustomBuild>
 </ItemGroup>

Two filters have the same ts file. It leads that the vcxproj file can not be loaded
