Mysterious print problem

I want to use two scripts for printing to a HP OfficeJet Pro 8600 printer, one for portrait and one for landscape. However, when I set the print step in one script and
then the second script, the setting in the first script switches itself to the setting in the second script!

 

For example: I set script A to landscape and then set script B and to portrait. When I check script A the setting has switched itself from landscape to portrait!

 

What can be causing this?
