Instant watermarking makes watermark on every image no matter if it’s turned on or off. Latest update didn’t change anything. Trying to use another watermark also fails, DxO is only using the first one created and on every image.
Check your export dialogue. There is a checkbox labeled “Override Watermark”. Uncheck this box to stop watermarking. You will have to do this for each export file type that you use.
Thanks! That solved my problem.
