Remove "Popular pages in Chrome" which downloads when the phone if offline

Hi

I have a OnePlus 5 and using Google Chrome and Android. When my phone is offline I get this issue. Normally I turn my phone offline at night or at family dinner - chrome seems to download pages offline and it takes almost 100mb of the phone...

I want to disable this and I find it privacy annoying.

Would appreciate help.

This article seems different to my issue: productforums.google.com/forum/#!topic/chrome/llxyqvGoim0

Note; I get notifications about this and then the download tab opens and it says "Popular pages from Chrome". See both screenshots attached:
