Scrape skipped pages

Hi there, I was trying to scrape this website: https://resources.hse.gov.uk/notices/notices/notice_list.asp?PN=1&ST=N&rdoNType=&NT=&SN=F&EO=LIKE&SF=RN&SV=&SO=DNIS

I followed a video and on your website and did the link- multiple- selected both roots and pagination. However, the scrapper jumps from 1 to 10, then 11, then 20 then 21 and so on. I have no idea how to solve this, could you help please? Thanks a lot
