Trendline erases chart name

[Guest]

When I add a trendline, the chart name gets changed to "Chart Title." The
name can be seen in the Chart Objects drop box, if I scroll down enough. When
I add the tendline, I'm leaving the Chart Title box marked as automatic, but
it still replaces the name to Chart Title. (The name on my charts just comes
from the data field that is above numerical data when I create the chart.)
I have a lot of charts to go through, >100, so any help in retaining the
name without having to retype it would be greatly appreciated.

Thanks!

I cannot think how this can happen. Email me the file (my private email, NOT
