You need to give the TOC2 Style the same right-hand tab stop and indent positioning as the TOC1 Style. To do that, click on the paragraph marker for any TOC2 entry in the Table of Contents, then go to:
• Paragraph>After Text and input -0.33cm
• Paragraph>Tabs and clear the 16.34 cm setting, then add a 15.6cm setting with a dot leader.

PS: I note you have created the Table of Contents via Word's References>Table of Contents function. A Table of Contents inserted that way is placed inside a form of content control whose performance degrades markedly as the Table of Contents grows. You'll get better performance by creating one via Insert|Quick Parts|Field>TOC.
