Importing Custom Data: Import of multiselect-fields for fieldgroup with multiple records not possible
I'm trying to import custom data to a custom field group with multiple records for a client.
In this field group I have a checkbox (multiselect) field.
In my import CSV I use the format "1,2,3" as a value for this multiselect field. Yet this value - even though it is possible when entering data manually - simply won't be accepted when importing via CSV.
Just to examine this behaviour further, I tried the same thing with a field group that doesn't allow mutliple records. Here the format "1,2,3" works as expected for my checkbox / multiselect field and gets imported without problems.
It should be possible to import multiselect fields for custom data with multiple records - so this seems like a bug at first glance. Or maybe I'm overseeing something here?
