Default blank row on insert of non main repeating table

[faivre]

Hello,

I am trying to prevent a default blank row being inserted into a
different repeating table when I insert into another repeating table.
I am able to prevent this from happening on the "main repeating table"
under "Form Options" -> "Default Values" I can "Select the fields and
groups to insert in the main data source when a user creates a new
form". However on other repeating tables if I insert a row it
automatically inserts a blank row in the other repeating table(s)
(excluding the main table). How can I prevent this from happening?

Thanks,

Brian
