Nuendo 11 doesn’t update exported wave file when accepting overwrite before exporting

I’m having this strange behavior on OS X Mojave and N11. Today I did a Dialogue insert on a project previously exported, and exporting that new file, with the same name as the one previously exported, and checking the “overwrite “ boxes, didn’t updated the previous file, only changing the name scheme did the job. Tried every checkbox and options on the export window and couldn’t solve the issue.
Am I missing something?

Appreciate any kind of help.
