Barcode function

I would like to use the barcode function and have activated the module for this (13.0.0).
In the module settings view, Dolibarr can graphically display all codes.

I have set the EAN13 code under further options - parameters. (Product and partner)
Under “Manager for the automatic generation of barcode numbers (product)” I entered the mask 300999 {000000} as a test.
“Deactivated” is displayed as the status.

Now my problem: I cannot toggle the “Deactivated” switch to “Activated”. The status remains on “deactivated”

How can I solve the problem?
Thank you for your help.

SOLVED:
When trying to activate the Barcode automatic generation, the “toggle on” button is not working. It is a bug in version 13.0 !
The problem result in the wrong URL where it is a missing n letter in the word “on” : “setbarcodeproducto” instead of “setbarcodeproducton” in barcode.php
correct to “setbarcodeproducton” and all is working fine.
