Funny bug with the export function: The function to Export with Previous does not work when the previous export was a User Preset. It's the previous previous setting that is then used.

I cannot reproduce on Mac 10.14.6 with Lightroom Classic 8.4. If someone would like to write out step by step instructions so that we are certain we aren't missing anything, I would be happy to try again.
As you can see: 1) I export using my preset: simple JPEG, quality at 100% to the desktop 2) I export "with previous" --> in renders a TIFF in a named folder. That's what I've used before.
Ok, Antoine, I was using the Menu commands at the top. I cannot get it to fail there. I can get it to fail with the context (right-click). I will log a bug.
Updates to Lightroom Classic, Camera Raw, and the Lightroom Ecosystem were released yesterday and contain a fix for this issue. Please install the appropriate update and see if it solves this problem. You can read more about the updates here.
