What happened to my scan icon

A while ago, I created a "Scan" icon on my tool bar, to make it quicker
to scan a page.  However, that icon seems to have disappeared.  Why is
it now gone?  Who was the genius who decided it was OK to interfere with
using LO?  That's 2 issues I've found in the past few minutes.  First,
most of my templates have disappeared and now this icon is gone.

Again, this is with LO 6.0.42.
