Some settings don't save, they revert back to original

I’m changing settings and clicking SAVE, it says “Settings successfully saved”, but returning to find my choices are not saved, in some cases. Examples :

  1. (System) Settings > General > Disable the Sidebar > YES (but it reverts to NO)

  2. (System) Settings > General > Send all outgoing emails as BCC to the admin account

YES (but it reverts to NO)

  1. (System) Settings > Invoices > Include ZUGFeRD > YES (but it reverts to NO)

Thanks

Everything works as expected here, no reverting on version 1.4.10.
Do you use the 1.5.0 beta?
