Batch processing issue - first file saved to specified (correct) folder and the rest to the wrong folder

Per the title, I am processing 300 images at a time, from DJI DNG to JPG.

I specify a folder as per the attached screenshot but only the first processed image is saved there. The other 299 are saved in a different folder, usually one used previously.

Also the first processed image is saved as image 2, not image 1.

See below where images were saved

Makes cataloguing very frustrating…

Not fixed in the new update…
