I have the same issue too. I really want to clear it or see a default location.
it used to work from a default location. but that stopped working 2 years ago.

I am having the same issue, started about a month ago.  I would describe it a little differently though, not sure if it is exactly the same.

If I have an image which I’ve uploaded into a board and then cropped in a specific way, when I selected the image, I used to be able to replace the image via “Upload new image from device” in the menu from the “replace Image” button.  The new image would retain the custom crop of the old image, which is the desired behavior.  Now the crop appears to reset to the center of the image.  This messes up a lot of my workflow.  If there is a way to reset the behavior to the way it worked before, that would be amazing.  Thanks!!!
