This error happened on the production server. I was unable to reproduce it on a local installation and was unable to clearly identify the source issue. It seems that the KeyError is raised because the string ‘..page-title.children…learn-more-button.children….....…stat_selection.options..’ is not a correct key. The elements of this string are all individual keys. This error does not happen on a regular basis.

This issue will be further looked into if it reoccurs more frequently.
