Duplicate meta description and page titles

Hi,

We are using software called screaming frog that gives us information about our site such as broken links etc. But it also shows us that we have a lot of duplicate information such as page titles and meta descriptions which seems to be caused by products that have more than one size or category pages that have multiple pages.

I think I have brought this problem up before and I’m still unsure on how to fix it and what needs to be done to resolve it. Is it something that needs to be done by me or can it be sorted on your side.

Thanks
