I can reproduce this every single time.
The attachments demonstrate.
Using v8.26:
file 1. A simple RTF file with no Metadata. I made this for the test.
files 2 & 3. epub made from RTF, Mobi made from epub. All perfect.
I then Deleted the epub and mobi files leaving the RTF and thus the settings in place
Then upgraded again to v8.27:
files 4 & 5, epub made from RTF and mobi made from epub. Mobi now has 2 sets of metadata.
Since I did an upgrade from 8.26 to 8.27 not a clean install and I did not remove the book in RTF format, it follows that the per book settings remained. thus it must be something in 8.27 which is causing this - or am I missing something?
I note the odd inclusion of the "-->" and "--", but you covered that in a previous thread, could this be connected?
