Can't delete parts of 'tailor your return'

My employment history is incorrect so I am trying to change it. I keep receiving this message: 'You cannot remove a section from within '3. Tailor your return'. Please use the 'Delete' link from within the section you wish to remove. The 'Delete' link can be found in the bottom right hand corner of the page. Go to Check your progress to access the relevant section.' There is no delete link that I can see on the bottom right hand corner of the page.

Hi Christopher Trim,
On the online tax return there should be a delete link on the page. If you are unable to find this link please contact our online helpdesk
for assistance. Technical support with HMRC online services
If you think the employment history we hold for you is incorrect you will need to contact HMRC to review. Contact HMRC
Thank you.
