Element Click Selector stops after a while

Describe the problem.
Hey guys,

I have been working on scraping blogs in the recent weeks, but for some reason I have some troubles with scraping the blog of the enclosed link. I have integrted the elementclick selector, to identify all link blogs, but somehow the scraper does not scrape all the links, but stops after 130 links.
Does anyone have a hint for me?

Best
Tevin
