When opening CopyTrans Manager these tracks are marked with a red circle.
How to solve this issue?
We’re already working on a fix and will release an update as soon as possible. In the meanwhile please just remove all files marked with a red circle using CopyTrans Manager and add them once again in smaller batches (e.g. 40 tracks/videos per sync). If that doesn’t work, follow the solutions from the following article.
Avoid grayed songs on iPhone, iPod Touch or iPad using iOS 5, 6 or 7?
To avoid grayed tracks, or tracks marked by a red circle in CopyTrans Manager, please just add small quantities of media files at once, e.g. no more than 40 tracks/videos at the same time.
