Extra checkout fields not saved or available in order details / reports

Hello,

I’m having trouble with extra checkout fields.

I’m using the plugin checkout field editor for Woocommerce ( plugin company Themehigh)

This has work perfectly for over a year. Now the plugin is broken.

The 2 extra fields are available on my checkout page for customers. Only when the order has been completed it seems that the data that was given isn’t their.

In the order details i can’t find the extra field data, also the order report shows nothing.

The 2 fields are

billing_leerling

billing_klas

The have been configured as a required field.

Also contacted the developer but the plugin should work

Any one an idee of what could be wrong.
