Xcode: Atos does not provide symbol information for CoreMotion function

Question

I am having troubles analyzing following crash report:

I am using atos with dSYM file from iTunes Connect (matching UUID) but I do not get symbol information for CoreMotion, and other symbols are somehow weird... Since I cannot reproduce the crash on my side I am completely stuck. Maybe somebody can give me a hint what's going wrong here?
