Hello, and thanks for the very quick response!
By 'next photo', I'm referring to when I enter a caption in the Metadata info field, I then click on the "Save & ->" button to advance to the next photo. When I do that, the previous caption I've written stays in the Description/Caption: box, when it should be blank or contain the standard .xmp file I have pre-loaded into all of the images.
I generally only work with .jpg files, especially when using PM for sports photography, which I primarily use it with. And it happens with images from multiple cameras (I shoot primarily with two Sony a9ii bodies).
While I usually use that "save & ->' button when entering caption info, I did try your suggestion of clicking OK, then going back to the contact sheet, enlarging the next image and then clicking the "I" to get into the metadata entry area, and it's the same result.
HOWEVER...after testing this further, it seems that the caption/metadata info IS actually refreshing, but it takes several seconds for the old caption to disappear and the new, black area to appear on each image. I'm wondering if there's a cache setting perhaps that's keeping it from immediately refreshing when moving to the 'next' image?
I have not tried downloading and installing a previous build to see if that fixes the issue yet.
