I have this solved myself.
It turned out that although I have installed the location map data through plugin installation, when I went to the server to check it, the folder was created but nothing was there. I don’t remember where but I found a link on here explaining how to install it manually. Basically you just need to jump on your server and copy those data to a specific folder, which I did. Then I came back to press that button again, everything went smoothly.
