Cannot run Referenced model in accelerator mode

I am unable to run a referenced model in accelerator, I have no issue doing so when the model is opened as the top model but once it is included in another model and individually set to accelerator while the rest of the model is set to normal, then it doesnt work.

Invalid run-time parameter registration in S-function 'sfun_spssw_discc' in model 'MyModel'. An S-function can register run-time parameters only if the S-function is being inlined. To be able to reference the model 'MyModel', the S-function 'sfun_spssw_discc' needs to set the option SS_OPTION_USE_TLC_WITH_ACCELERATOR and it needs to have a TLC file.

I am not intentionally using any S - functions so I am a little unsure what to do with this error message

@Jake Gareau, Can you provide the simulink models so that I can take a look to find the issue.
