flowed tables not reacting as expected

My form tracks contract dollars paid and change orders added. both change orders and payment tables are dynamic flowed subforms. When I add more lines to one or the other that exceeds the page limit the following happens: the left table pushes the right table to the next page when the left table exceeds the limit. Also if the right table overwrites the left table when it exceeds the page limit. Each is in its' own subform and each is Flowed, Western Text, Allow Page Breaks  within Content and use default pagination. The top of the form is a Position subform. I have attached a screenshot of the form.

Any help is appreciated.
