T21 code causes invoice problems - additional 0.00 and *

SUGGESTED

When I use the code T21 for reverse charge VAT the system adds a * at the start of the details column and if the words wrap around it adds 0.00 in the amount column - this only shows when I go to print it does not come up on the screen.

When I use T1 for standard VAT this does not happen.

It is driving me crazy.

Anybody help me with this?

Thanks
