Sequence diagram being changed

I’m evaluating VP using Community Edition, and am having a small problem with a Sequence diagram.

I had created a rather simple sequence diagram and had everything just the way I wanted it. I saved it, and closed VP. The next day when I opened the project, some of the connectors in the sequence diagram were pointing the opposite direction and some were even connecting different things. This has happened several times, so it’s not someone just messing with it.

It’s the way I want it, I save it, I close it, I open it again, and some things are changed. What’s happening?

Thanks.

Dear Nathan,

Could you please let me know which version and build are you using?

Best Regards,
Jick
