A set of buttons is no longer working and I can't work out why.

The site is using Joomla and SP Page Builder Pro.

There are 3 buttons that when clicked will change the price table. However these no longer work and there's no errors in the console.

If I enter the function name into the console, the script will trigger and change the table.

Debugging steps: Updated Joomla
Disabled non required plugins
Cleared cache
Checked code is being loaded
Checked for java conflicts

Many thanks
