Strip HTML Elements by XPATH/CSS Selector does not work

Hi, I'm new here and working my way into Crawlomatic. I can't get two problems solved. 1) I want to crawl the content of a blog. But I always want only the first five articles. If I crawl every 12 hours the plugin crawls the first five the first time, the second five the second time and so on. How can I set this to always crawl only the first five posts. 2) I crawl a press portal. From the result I want to remove some elements. I tried it with "Strip HTML Elements by Class:" and "Strip HTML Elements by XPATH/CSS Selector:". But unfortunately it does not work. Below is the address of a sample page: https://www.presseportal.de/blaulicht/pm/24843/5115998 Thanks a lot for your help. I am very pleased with the plugin Greetings from meckerman
