Two bins are not fitting properly

Dear Experts,

I am trying to fit bs mass with double gaussian(signal) and gaussian+exponetial (background). The fit status shows good, but there is two bins(peak one around 5.36 and another around 5.31) which are not fitted properly. I am attaching the plot and code. Could you please tell me how to fit these two bins?

Thanks,
Deepak

We are missing the data you are using in this macro. We cannot run it.
