Hi, first of all I want to thank you for your answer.
I've discovered the existence of these urls by using siteliner, a reliable website that crawls sites so as to see duplicate content, broken links etc...
I have seen these urls here first. Unfortunately I have noticed that they actually exist. It was not a crawl analysis mistake.
Even if these urls are so many, it seems that they are not being seen as duplicate content (website duplicate content seems to be only 2%). It is the first time I see something similar.
It is like they are duplicate pages with different urls of courses category and actual courses pages.
I might use exact match redirect to be sure I will not be affected by duplicate/poor content issues but I would need to do that operation for more than 100 urls and I still wouldn't know how it is possible they actually exist. I need to understand that in order to avoid the same issue to rise next courses I will publish.
Please tell me what do you think it may have generated so many urls or if you need more details.
If there is any option to put some links in private without opening a ticket I can give you directly the siteliner analysis link and some of the duplicate urls in the website.
Thanks in advance for your help and support.
Have a good day.
