Editing Mail – WooCommerce Email Template Customizer

Please could you check if there are any issue by editing mail on WooCommerce Email Template Customizer ?

Im back to edit mail after a while and i discover that mail are impossible to edit.

Step to recreate issue.

1) Open a mail template

2) edit a single header text or removing widget

3) Click on UPDATE BUTTON

at this point the template refresh but without editing applied

Thank you soo much for the feedback; im using the 1.3.0 version by thameforest download.
