Adding roof to deck messes up house roof

[Murphyzoo]

I'm new to Home Designer and have Home Designer Pro (2021 Build 22.3.0.55x64 June 8, 2020).  I've been using the program for a few weeks to design and draw a deck and 3-season room addition for my house.  

Most everything is going well, however, when I try and add a roof over the deck on the side of the house, it messes up the roof over the vaulted front room of the house.

I'd like to find a way to get the side deck roof to be added and attach to the roof over the front porch without changing the roof over the front vaulted room of the house.

 

Here's a picture of the house with the correct roof over the front room:

 

When I add the roof over the side deck, this is what Home Designer does:

 

I'm not sure how to modify the walls/roof settings to get this to work correctly.

Any ideas?

 

Thank you,

Brian

Thank you both for the help here.  The video you put together was great and will really help me here.   You basically got the roof to be what I wanted.      I've struggled with manual roof planes and have watched several tutorials, but seeing it on my plan really helped.

 

Thank you,
