Hi,
Can you please provide more details about the shipping address and your paypal plugin configuration ?
Are you using a "shipping address override" with your shipping methods ?
About the "capture", it is something link to the "Enable validation mode" option.

By the way, do not send me private message, use the "contact us" form instead.
