Please follow the steps mentioned below.
- Rename the Sync.lrdata File to Sync.Lrdata.old
- You can find the sync.lrdata file here:
- On Mac it's at /Users//Library/Caches/Adobe/Lightroom/Sync Data/Sync.lrdata
- On Win it would be at C:\Users\\AppData\Local\Adobe\Lightroom\Caches\Sync Data\Sync.lrdata
Once done Restart Lightroom should try to reconcile your local synced data and the cloud synced data.
Let us know if that helps
I have deleted the cache and signed out and in to LR without any success.

Will you be able to delete/move those 300 files that do not sync?
You can see the list of those images in Lightroom >>Preferences>>Lightroom mobile>>Sync status.
