Hey Tuktop,
thank you for the demo :)
I’ve improved the code that generates the column shortcodes in the first place, so that no workarounds are needed – please download this archive, unzip it, and upload the resulting file into the following folder:
/wp-content/plugins/shortcodes/lib
replacing the existing file.
Let me know if it works better now with the fix!
Sincerely,
Andrii / Satori Studio
