I draw on the wisdom of the community:
I have created a series2 column and set it in the metadata plugboard like this:
any format / Kindle2
{series:||}{series_index:0>2s|: | - } {#series2:||}{#series2_index:0>2s|: | - } {title} in title field
When passing it to the kindle, an unknown series2 field error appears.
How could I add a second series on the device?
