Hello. Thank you for contacting the Toolset support.
That is really strange and I'm not sure that button element you are using is from Toolset? as Toolset do not offer such button shortcocde.
Can you please share problem URL and admin access details and I'm happy to review and check whats going wrong with your setup.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
