Unable to delete cloned theme

Hi,

after successfully using wp clone for two sites I am now unable to delete the theme that was cloned. After selecting Delete and then shows down the bottom of wp that the theme is broke.

———————————-
Broken Themes

The following themes are installed but incomplete. Themes must have a stylesheet and a template.

Name Description
directorypress Stylesheet is missing.

——————————–
I then try to install the new updated theme but this fails as it states the theme already exists.
Please help as I need to update my theme.
