Why does my blog page schema only run 50 times instead of 81?

[Anonymous]

Hi, I am working on blog page schema - https://www.indiquehair.com/blogs/indique-blog

There are total 81 Indique blogs as on date. Article count "blog.articles_count" returns correct value and all 81 blocks gets displayed in schema but last 31 article data is not accessible and hence it throws error while testing.
If I do not consider this count and loop through the articles using "blog.articles" then it runs only 50 times. I am unable to figure out what's wrong because those articles have proper data.

"blog.articles" is working fine while displaying data in section file.

For now I have skipped that 31 articles in code just to avoid any error that Google structured data testing tool can throw.

I have written code in template file. If I shift this code to section file, then also the same error exists. What can be the possible solution to this?
