In Visual Paradigm, how to have a solid line, rather than a dotted line, towards a class that is created later down the timeline?

Question

I am creating a sequence diagram and I would like the diagram to appear as follows, where the OnlineCart object is placed downwards on the timeline with a solid arrow going towards it:

However, when I try this on visual paradigm, if I use a solid line then the Reservation class appears at the top, and only with a dashed line does it appear where I want it (as shown in the second image). What is the reason for this, and is there any bypass to get a solid line, as that is what is used in my textbook diagrams?

P. 720 of UML 2.5 shows the create message:

As you can see this is a dashed line. Which means your first picture is wrong in this respect and the second one is correct.

Many lecture questions I've seen here refer to simply wrong examples from teachers. Sad, but true. Keep it with Gershwin: It Ain't Necessarily So
