Unable to tag multiple items

Trying to tag items as “website” for example via Bulky (Version 1.2.3 paid license) and when I copy the existing tag to a new field or cell, it’s coming up as “undefined; undefined; undefined…” When I click into the cell, it has the word [ o b j e c t ] which each individual letter as a separate tag?

Please let me know if you need my site information to login.
