Pediatric LoR for IM

This would be my second cycle and I am really skeptical about applying again. I am a Non-US IMG with Pass/236/213 scores. I am currently rotating in a clinic near Chicago. The attending has done combined IM Peds Residency. In the clinic both the adult and pediatric population is checked. The LoR which the attending will provide will be on the clinic name, which is related to Pediatric. So would this cause any issue, if the LoR is on the clinic name (Pediatric Clinic) but recommend me for IM/FM. I need suggestions in this regard.
