Automatically inserted a line break when trying to join table sections which both are in a control

When trying to create a template within Word (through documentscorepack for CRM), I want to join two table sections which are both in diffrent controls. The problem I am facing is when I have two table sections which are both in a control, a break is always being added after the table section that I can't seem to get rid of. 

This problem doesn't seem to occur when I just work with text, nor when I trie to do this within one condition. 

Does anyone have an idea how to remove this line break?
