How to combine the starting point of two messages

Hi, all!
I am a beginner in Visual Paradigm.Accidentally I combined the starting point of the two reply messages within sequence diagram, but did not understand how this happened.
I want to repeat, but it doesn’t work
Tell me, please, what should be done with two parallel messages so that their starting points coincide?

Hi Lev,

Just set “Branch Parent Message” to Unspecified as shown in the screenshot.


Best Regards,


Oooo, thanks a lot, Antony!
