What happened?
That document is not well presented. It doesn't describe the issue and the relation with the setting to touch. After the first reading it doesn't even feel as a troubleshooting doc and the statement To fix this issue, complete the following steps feels out of place.
I'd suggest to rewrite the introduction in the future so it feels better landed in this troubleshooting section.
Additional info
There are other similar troubleshooting pages facing the same type of issue in the introduction.
