Duplicate Title Tags on category?page=2

My store have got some warnings from Google Serach Console concerning "dplicate title tags" by pages with links ?page=2. I have checked the links with this issue. They are category on page2. All category pages with ?page=2 don’t have rel="canonical" for sampel https://xyz.com/category?page=2, but categories with ?page=3 have rel="canonical" for sampel https://xyz.com/category?page=3

It means that https://xyz.com/category and https://xyz.com/category?page=2 have duplicate title tags, because there is no rel="canonical" on https://xyz.com/category?page=2, so Google says that they have duplicate title tags.

The source code on page=2
<link href="https://xyz.com/category" rel="prev" />
<link href="https://xyz.com/category?page=3" rel="next" />

The sorce code on page=3
<link href="https://xyz.com/category" rel="canonical" />
<link href="https://xyz.com/category?page=2" rel="prev" />
<link href="https://xyz.com/category?page=4" rel="next" />

You need a SEO extension, which fixes this. Our Smart SEO Pack can do that. It fixes prev/next tags, adds canonical URLs everywhere and does tons of different things under the hood.

If you have any questions, feel free to drop me an email to support@thekrotek.com.

My store has an SEO extension which has added canonical URLs, but not on ?page=2 on categories. The name of the extension is "ALL IN ONE SEO PACK" https://www.opencart.com/index.php?rout ... on_id=7540
I have sent this issue to theirs support email address. But they haven't replied me yet.

Guess, you need to wait for their reply then.
