When using clone as multiple, the data is saved to the database as a serialized array when it should be saved to multiple rows instead. Furthermore, the edit page only displays the first of the three taxonomy terms that were selected:
When clone as multiple is disabled, the edit page displays all three of the selected categories - cloning works as expected.
Related to this, if I manually create three rows for this taxonomy advanced field when clone as multiple is enabled, then only the first row shows up on the edit page.
- The "clone as multiple" feature doesn't save taxonomy advanced field data in multiple rows.
- The "clone as multiple" feature only displays one row of data belonging to taxonomy advanced fields.
