BUG: Menuboard -> Product availability can not be switched

CMS Version

4.2.1

Issue

Xibo offers for menuboard product the option to switch the “availability”.
But button “switching off” is not considered after product saving.
Product option is still “availability on” (instead of off).

Please fix.

Steps to reproduce:

  1. create a menuboard “M1”, category “C1” and product “P1”
  2. go to EDIT product p1
  3. use “Availability button” to switch-off
  4. Press Save
  5. product still set to “available”
