I need help with blog page

I created a blog page with 12 blogs and then tried to link them to my blogs in my collections. When trying to connect them somehow each blog has multiplied 50 fold for each blog that now show around 50 repeats of each blog on the main blog page ? Does anybody know what I did wrong as still showing 12 elements on loop. Any help would be great :|)
Thanks

Hello, paste url and images Inhere. Looks like you connected wrong element to the collection but would be nice to see how did you connected elements.

WojciechK thanks for your input :)) I reached out through chat and fixed the problem. Much appreciated
