problem importing MXF. files into p.pro. from Panasonic P2 card.

I copy the contents of my sdhc card to a folder on a hard drive before importing, but do nothing to the card folder structure.  nope, when I use media browser and click on the either the containing folder, the private folder or the avchd icon (which apple in all it's wisdom has now called an avchd collection rather than a folder), I get individual clips with a 0 hr timecode start and a spanned clip with the correct starting timecode.   Am I doing something wrong?   Spent a fair amount of time trying to figure this out about a year or so ago...  

I've seen this problem with avchd files brought in using the media browser in CC2018.  Not really a problem as it just takes a minute to delete the unnecessary clips.   Haven't tried it in 2019.  Will try it and see if it makes a difference.  

Also, gotta say I often just bite the bullet and use editready to transcode the clips to prores422.  I sometimes need to do a color correct in resolve and find that spanned clips do not come over correctly in an xml exported from premiere.  Again haven't tried this in 2019 (or 2020) and can't rule out operator error...

I'm guessing that these clips are "spanned" files.  Unfortunately many video formats are limited to a relatively small file size by the legacy partition format of the recording disk or chip.  Using a program like editready to convert the clips to a more flexible format like prores solves the problem.  But just deleting these "duplicate" files should solve the problem.   

This usually happens when/if you rename the folder CONTENTS and/or it´s subfolders. The key is to always keep the original folder structure.

Importing using File > Import gives the same result, so using the Media Browser to import is better.
