Kingdom Customization Error

[Lord Moontree.]

Hi everyone! Maybe user error, but I'm getting the following error saying I have more points to spend, but unless I can't do simple addition, it seems like my options add up to 20. Should I ignore this error or am I doing something wrong?

ERROR MESSAGES:

This occurs when you choose the +15k defense item. As others noted, track your choices; you can also leave that option for last.
