Hey See22,
first of all, thank you for the purchase!
I sincerely apologize, this is indeed my mistake in the code. I’ve prepared a fix – please download this archive, unzip it, and upload the contained file into the theme folder via ftp (/wp-content/themes/Kanso/), replacing the existing file. Let me know if the bug persists after this!
Best,
Andrii / Satori Studio
