SCC file import is not accurate

I often have to retime closed captions so I import my feature and import my SCC then get them so that they are in sync. then export both out.

What I'm finding seems to occur when music symbols are used.  If the caption has one line of text/lyrics and a music symbol at the head and at the end, the end symbol is cut out on import. At times it also removes text within the line.

Perhaps the caption functioning is not meant for this simple use.  WhenI reported this to support they asked if it does the same thing when I'm creating captions.  That's really is not the point of what I'm doing.  I'm simply tryign to import an scc file that I know is good, re-time it to picture, then re-export.

Does anyone know if there are preferances for how captioning is handled in Premiere on import?

Thanks!
