problem with dll compiled in VS2015

Hello,
We use SDL Passolo 2011. After porting one of our projects to Visual Studio 2015 (previously we used Visual Studio 2013), Passolo started to fail to parse one of the dll files. The error report shows that many resources have "Missing ParentName". When the same dll is compiled with Visual Studio 2013, Passolo parses it without problems. Any help is greatly appreciated.
