Error when transferring customization to child theme

Hi,

I have been trying to copy the customizer settings from a parent “astral” theme to “astral-child”. The export from the parent seems to go OK but when I try to import to the child I get the following message:

“ERROR importing settings! The settings you uploaded are not for the current theme.”

The steps I use are as follows: 1) with the customized parent theme activated, I export the customizer settings using Customezer Reset – Import & Export 2) activate the child theme which has no customization, 3) attempt to use CRI&E to import the settings from the parent. I am able to select the json file exported in step 1) and confirm that I will overwrite any existing customization. After pressing OK, the error quoted above is displayed. Upon pressing OK, the interface displays the unaltered child theme.

Am I missing something? Also, I cannot post a url to the site because it is hosted on my development server which is not publicly accessible.

Thanks in advance for any assistance.

Doug
