Two relatively small, and one that I had to downzise (very) much. Had them patched together and added a layer mask to one of them and made the merge. Worked even for the third pic.Then during the process of exporting the merge disappeared

Still a little short of info on your procedures but as a guess, using a gradient in a layer mask something like this



To finalise the gradient in Gimp 2.10 you have to hit the ENTER or choose another tool . The effect will be seen in the layer mask.



An alternative if not using the gradient tool. Use Layer -> New from Visible Does what it says. Move the visible layer to the top of the stack before exporting.
