(AppCode) Imported project created in XCode, breakpoints in sub-projects are skipped over

Hi! Forgive the potentially dumb question, but none of the people I'm working with have been able to figure this out either. I have an XCode project that is working as intended and fully configured for debugging that I would like to start working with in AppCode. The project contains a top level project with several sub-projects.  I opened my xcworkspace directly in AppCode and it opens and runs the project as intended without any further configuration (yay!).  I can also successfully edit and compile changes to the code within AppCode and it runs great.

Now, for debugging, I can set a breakpoint anywhere in the overall project within XCode and perform debug operations that location just fine.  In AppCode, I am able to place breakpoints anywhere in the same way and AppCode reports that they are reachable (ie. any breakpoint I set has a check mark). 

However, in trying to debug the project in AppCode, only breakpoints in the top-level project are actually automatically stopped at, any breakpoints in the sub-projects are skipped over.  I am able to step into
sub-project code from the top-level project though, so the code is in fact debuggable, but apparently just not seen by AppCode?

Why is this? Is this a configuration problem specific to AppCode? (If so, why isn't AppCode the exact same as XCode in this regard?) And most importantly, how can I fix this?

Example:

This code in the top-level project. This breakpoint is hit.

Next is the function immediately under the breakpoint above and contains its own breakpoint as well. This function is contained within sub-project of the top-level project. On execution, the top-level breakpoint is hit, but this one is not and is skipped over. I can step into this function from the above function call, but neither this breakpoint nor any other breakpoints in any sub-projects are ever hit.

Thanks!
