Only a few posts showing on admin page

Only a few posts are showing on my admin panel in All Posts on my new Dell Inspiron 14 2-in-1 laptop. However, all of my posts in All Posts show on my admin panel on my desktop admin panel. And I have set a specific number of posts to show on my admin panel.

I have had no posts to show on my desktop admin panel before, but all I had to do to make the posts show was to drag arrows to make the page wider. That solution didn’t work on my laptop, as you will see in the Vidyard screenshot.

Of course, I log into my admin panel the same way on both my desktop computer and my laptop.

Please tell me how to fix this problem on my admin panel on my laptop. I have to start using my laptop more because my husband is working from home more and uses the desktop computer. And I need to be able to get to my posts in my admin panel on my laptop to work on my posts.
