looks like you have two copies of the media (low res & high res?)
How did you bring your media in?
Where did it come from?…did you consolidate or transcode to a new folder inside Avid, then make a list and bring it over, or are you letting Resolve search for media by itself.
I would suggest you start by cleaning up your media inside Avid. Ensure you only have the 1 final copy of the clips online. That should help with the confusion of what is and isn’t available to Resolve.
Remember its just a program, being asked to look for media based on name/tc etc. If you presented a persion with the same task, and two options, they would get confused as well.
Inside Resolve, manually bring in the media you want Resolve to look at before you import your list. When you bring in your list, deselect the box asking Resolve to automatically bring in media clips.
When prompted, point Resolve to the media you previously imported.
Hopefully that helps.
