For the years that is in columns, click on the drop down and change it to 'discrete'. For the second question, click on the tooltip on the marks card for the bottom graphic and remove the long/lat fields from it.
Hope that helps.
I managed to remove the long/lat fields, but am unsure about what to do for the years. I found the columns by searching the the help menu but there is nothing on my Tableau that says discrete. I can only see options like show percentage/total.
Click on the dorpdown on the pill that you placed on columns (the year dimension) that is on the columns. When you click on the dropdown of the pill, you will see an option 'discrete' select that. The pill turns blue upon doing so. Hope you can find it. See the week pill, it should turn blue when its a discrete field:
