max pension contribution( acca practise hub)

Mobias will make an additional personal pension contribution for the tax year 2024-25, having already made contributions of £10,000 during this tax year. He has been self-employed since 6 April 2022, and has been a member of a personal pension scheme from the tax year 2023-24 onwards. Mobias’ trading profits and gross personal pension contributions since he commenced self-employment have been as follows:
Trading profit Pension contribution
Tax year £ £
2022-23 42,000 0
2023-24 53,000 46,000
2024-25 78,000 30,000

here i did it this way:
cont unused
23-24 46000 14000
24-25 30000 30000

so thought the max of still 44000 could be made

but in solution they said theres no max limit
