I had to delete your picture due to GDPR but I saw it. It works fine in the program to pay out a salary without paying out vacation. I don't know exactly what your settings look like in the background, so I think the easiest thing is to call our support who can guide you over the phone instead.
If you can't delete the lines directly on the pay slip, it may be because he has vacation settings in the employment register. When you create the employee from scratch, you can choose to have a simple employee and only pay out money but no vacation deduction, for example. Now afterwards you can change the employment type or vacation settings in the employee settings.
