Themes Description - Changes are not shown

When I change the description of a lightweight Theme in Edit Mode and save it again… I only can read the new Text in the Edit Mode… not in the Presentation there will be still shown the "old" Version… So what can I do…?

It may take up to a few minutes for a change to apply on the site. So, sometimes you’ll make an edit and you won’t see it reflected on the page until later.
