Media Offline - Typical link method did not work

Hello,

Looking for some help relinking files. I have tried the typical method, perhaps this situation is more complicated.

Long story short, the typical relink method did not link all files.

The files remaining to be linked did not appear in the Link Media exercise, and do not appear if I relaunch the feature.

It would appear there are files in the timeline which are not in the project.

Context

I have tried to convert my timeline from FCP to DaVinci to Adobe. Used this typical YouTube guide here.

The process began on my MAC, exported fcpxml from FCP then exported xml from Davini. On my PC, I opened premiere, opened the imported xml timeline and linked the files.

Some files have linked successfully. It would appear some items remaining did not link and do not offer the option to link.

I have confirmed these items do play in VLC thus they are not corrupted. I noticed in the timeline the unlinked files all have a percent next to the document title. Perhaps this is a critical clue. I can provide more details where it is perceived as relevant. The unlinked files were taken on an iPhone, perhaps this is a MAC/Pc compatibility issue?

More context.

1. I have noticed remaining unlinked files have a % indicated next to the project file in the timeline, pehraps this is a cooincidence or it is indicative of root of the ongoing issue.
