Concatenating Audio Results in One Channel Audio

Hello, we have been using the API successfully to concatenate audio files. It's a great feature.

However, we are experiencing an issue with some audio files we upload to our software that is used to send to your API.

The problem is this: When mixing some of the audio files (these are MP3 files created by ElevenLabs synthetic text to speech files), those play back within the concatenated file just in the left speaker. They are normal and play in both speakers prior to upload.

So, we might be concatenating several files, and only the files that are created by ElevenLabs (mp3s) play in one speaker. Could there be a parameter that's causing this or could you advise likely cause?
