Hey Unusual, Ajlitton,
firstly, please accept my apologies for the delay in my reply.
After an investigation I found that it’s indeed a bug in the function which saves post meta, thank you for reporting! I’ve created a fix, please download this archive, unzip it, and upload the resulting file into the following folder inside your WordPress install: /wp-content/themes/Ikebana/ – replacing the existing file. Should you face any difficulties with that, please let me know! I will also include the fix into the upcoming update of the core file on ThemeForest.
Sincerely,
Andrii / Satori Studio
