It is explained above. The file my-file.ext.part was edited, but then
at some point the file named changed during editing, or file may be
removed. After editing, the buffer was not refreshed. I could see new
file name in the buffer while that file did not exist.

With emacs -Q I see that it refreshes.

I can't understand why and how, that is what happened. I do not change
dired myself in anyway, even if not used with emacs -Q.
