In ACCA Taxation (TX-UK) (F6) Lectures, chapter 10 lecture videos, I have noticed that there is same video for both topics :
Types of Pension Scheme [35:19m] & Annual Allowance (AA) [17:29]
The link to both videos are AA, the second topic. So that means first one which is Types of Pension Scheme [35:19m] link is not correct and not available.
