Why does PSE12 try to save as 'Baseline Optimised' - how can I change default?

I recently had problems showing my saved .jpg files using an Epson Projector - it did not recognise them.  I worked out that this was because they had been saved as 'Baseline Optimsed' rather than the 'Baseline Standard' I always use.  I had to go through dozens of files and re-save them - they then worked.  But I now find that other files are by default being saved as 'Optimised' and I am finding it frustrating to have to remember to keep changing the box when I save. Is there any way to set 'Baseline Standard' as my default? And is there any way of my quickly identifying which files I might have saved using the wrong option - otherwise I will have a lot of work going through them all and re-saving those which are wrong.
