Hey Anders,
first of all, thank you for the purchase!
This is a known issue, and I’m currently finalizing a theme update to version 1.4 that will among other things include a fix. Meanwhile, you can download this archive, unzip it, and upload the resulting file into the theme folder (/wp-content/themes/Kanso), replacing the existing file. Please let me know if the fix works for you!
Sincerely,
Andrii / Satori Studio
