I am having problems with text breaking across pages in my document. From the picture, you can see that 'Section 2.2.2' is positioned poorly.

The problem seems to be due to the contents of Table 3.

I include 2 MWE's with pictures. The first MWE shows the problem. The second MWE contains the same code but with a different Table 3. The only difference between the two tables is the number of text strings.

Can someone suggest a reason and solution for this please?

MWE 1 (problem):
