Zerif lite child

Hi,

I have created a child theme for zerif lite, following the zerif child setup instructions.
When I go to dashboard/appearances/themes, I get the following error message:

Broken Themes
The following themes are installed but incomplete.
Name Description
Zerif Lite Child The parent theme is missing. Please install the “zerif-Lite-Child” parent theme.

The zerif-lite parent theme is installed.
Could anyone please assist me? ??
