Text and Images will not line up in posts/pages, all over the place.

My question is , all my clients are having the exact same problem when I use this theme.
When we add images and text wrap, the images get on top of each other or lay out in a decending pattern.
It is a mess. I am really getting worn out trying to figure this out for people.
I have resorted to inserting lines and coloring them white to make the sections stay apart.
I have about 8 Wordpress themes I use, (studio press) and this theme is the only one I have this issue with,
I love this theme but this is a deal breaker lately for me with clients.
It is very time consuming and I don't even know why it keeps happening. A reason and solution would be wonderful.

Thanks

I have this with all the Atahualpa themes I use.
I need to understand why this happening so I can fix it.

Thank you.
Also I did not know what thread is correct for this.
I did not see a general questions thread.
