Styling PDF Invoice - Joom Donation

Hi JD Folk:
We are trying to style the invoice that is sent to donor when they make payment.  We want to avoid going into the php files to make these changes. 

1. Spacing is strange and it goes on for two pages (see below).  We used the [DONATION_DETAIL] field tag.   See sample below and full invoice attached.

2. In another test we used all the individual tags, however if a field was not filled out, it would simply show the tag e.g. [ADDRESS2].

Thank you for your assistance.

The invoice appears like this:
First Name customer name


Last Name customer last name


Organization
company name


Address
444 some street



City name of city

ETC.

 

Hi, I'm also trying to style the PDF invoice but in Configuration page I cannot find the way to change how the DONATION DETAILS is formatted. I also try in the media/com_jdonation/assets/css/style.css but I was not able to make any changes.
Infact Donation Details are shown as a very long list with too much space between lines
Thank for your help
