Sequence of photos, shot in Burst mode on Nikon D500, is jeopardized when imported with name change

When I import a burst shot with Bridge Photodownloader the the sequence is lost when I also change the name at import. Without a name change the sequence is kept. Is this a known issue and error or do I make a mistake here? I insert two series of the same burst to demonstrate the issue: First without a name change, so as they come from the camera name starts with DSC_7273.jpg and ends at DSC_7287.jpg.; the second with a name change during import starts at 202102dec_1403.jpg and ends at 202102dec_1417.jpg. Strange enough the second serie with the name change is also more or less reversed and the entire sequence is disrupted. My Nikon D850 has the same problem and also with the photos taken with focus-stacking. Especially with focusstacking this is not very nice, need to restore the sequence manually. Is this a Bug and can it be resolved? Any Clue? (Brigde version 12.0.0.234).
