Drop drown menu's with html that remains constant

Describe the problem.
I am working on the Whoscored website and am trying to scrape match event data for a whole season. Who scored has a drop down menu to select the year and month in which you want to view, however the html link remains constant when clicking through each month. Once my scraper has selected a match within a month and then moves to the next match, the scraper reverts back to the most recent month of matches. There seems to be a loop not allowing the scraper to go through each month.
