Mac load commands corruption

Signing (codesign) on one of our app is failing with malformed object (unknown load command 9). After doing some research online I found that load commands are special commands in executable's header that are used by kernel for segment loading ( http://0xfe.blogspot.in/2006/03/how-os-x-executes-applications.html ). So, I ran otool -l command on my app. Where I found that and command 30 were corrupt. But, launching app works absolutely fine.

How can I resolve this issue? I have no idea about how other team built that app.

The otool -l command snippet

@Gagandeep Singh already figured out a solution, but for others who come across this question:

"Unknown load command" errors can happen when an object is built for one Mac OS X version and then used on an earlier Mac OS X version.

Mac OS X 10.6 introduced load command LC_DYLD_INFO_ONLY (0×80000022). To fix problems with that, see here.

Mac OS X 10.7 introduced load commands LC_VERSION_MIN_MACOSX (0×80000024) and LC_FUNCTION_STARTS (0x80000026). To fix problems with those, see here.

A handy list of load command names is in mach-o/loader.h.
