...the report shows elsewhere that vaccinated adults are now being infected at much HIGHER rates than the unvaccinated).

This is Table 2 (page 13). This phenomenon applies to ages 30 and older and is discussed on the previous page.

This is likely to be due to a variety of reasons, including differences in the population of vaccinated and unvaccinated people as well as differences in testing patterns.

The vaccination status of cases...is not the most appropriate method to assess vaccine effectiveness and there is a high risk of misinterpretation.

In the context of very high vaccine coverage in the population, even with a highly effective vaccine, it is expected that a large proportion of cases...would occur in vaccinated individuals, simply because a larger proportion of the population are vaccinated than unvaccinated and no vaccine is 100% effective. This is especially true because vaccination has been prioritised in individuals who are more susceptible or more at risk of severe disease.

The case rates in the vaccinated and unvaccinated populations are crude rates that do not take into account underlying statistical biases in the data. There are likely to be systematic differences in who chooses to be tested and the COVID risk of people who are vaccinated. These biases become more evident as more people are vaccinated and the differences between the vaccinated and unvaccinated population become systematically different in ways that are not accounted for without undertaken formal analysis of vaccine effectiveness as is made clear.
