JPEG export sometimes set back to low quality export


For some reason, the export settings when using JPEG keeps on going back to the original low resolution value. This happens even in a scene I’ve been working on for many days without changing anything to the Setup List. Each time I am ready to start batch exporting, I need to double-check if the JPEG is set to maximum quality. Very often, and randomly it goes back to low resolution.

Thank you for you help.
