Places I have visited

In the maps app there is a section that shows on the bottom of the screen in timeline. It is titled “visited and most visited”. You can tap on with one and it takes you to visited or most visited places you have been. So, you scroll and see the places you have been with date and info. So I come across 2 places, showing a gray dot next to them. I think most are brown dotted. And they are blank. This is a list of places. In order. So I guess 2 are not showing. Can I retrieve the info of these two places? I tapped keyboard shortcuts. And I see options. Any one know what I can do to show these 2 places? Thank you!
