Google Not indexing certain pages - Sitemap can be read but has errors, HTML

Hi, 

I have managed to get most of my pages indexed by Google, however, certain ones are not coming up due to "error found" - 

The error is that the sites are in HTML. I am brand new to this, the only thing I can think of is that the template I have picked for these certain Pages within my site are set up differently. How can I fix this issue?

it applies to these pages within my site:

www.optisportsphysio.com.au/news (and the blog posts within)

www.optisportsphysio.com.au/team

Thanks

I just added it - I'm assuming it will take some time to index the other sites now that the sitemap has been submitted?

I was using sitemap instead of the URL inspection tool to get pages added. Thank you for your help!
