Invalid Email address SmartSuite to Kit

I am attempting to move data from smartsuite to Kit/Convert kit.

When I attempt to move data from SmartSuite to Kit I get an invalid email address.

To troubleshoot I sent data from smartsuite to google sheets. The data appears correct in google sheets.

What I think is happening is that smartsuite is sending data that may include brackets. Example [email@address.com] where conver kit needs the data to be email@address.com

What are the exact steps I could take to remove brackets from a data string coming from smart suite to Kit.
