I have now tried:
1. Removing the characters column in the custom columns settings, and added the part to the default section.
Code:
[defaults]
add_to_custom_columns_settings:
characters=>#characters,a
- That didn't work, it still removes the existing characters when I add new ones.
2. Added the column for characters in the custom column settings and a checkmark in "New Only" and the site specific metadata.
Code:
[www.storiesofarda.com]
custom_columns_settings:
characters=>#characters,a
- That didn't work neither.
I've restarted calibre in-between each try in case the plugin needed that. This problem only exists when I try to add new characters to multiple stories at once.
