I thought I was having an issue as well, but you have to select the wall you want to upgrade, not what you want to upgrade to. For example, I have level 7 walls, I want them upgraded to level 8. In the selection area, you select level 7 walls. I originally thought you had to select the type of wall you wanted to be upgraded as a result. I noticed this because when I started the bot, it gave me an error message telling me I had to be a town hall 9 to upgrade the wall. Hope this helps!
