SUMMARY After Neon install (fresh install from neon-user-20221023-0714.iso) with en_US regional settings the "Paper Size" is "Letter". Selecting different local with "A4" size seems to be ignored. (didn't restart/relogin yet to confirm whether this is just visual bug, or the setting is really ignored). STEPS TO REPRODUCE 1. have `LC_PAPER=en_US.UTF-8` initially, enter Region & Language settings 2. Paper Size should show value "Letter", hit "Modify..." 3. Select some other country with "A4" value like for example cs_CZ (čeština) 4. see the Paper Size row still show "Letter" value. Other rows display newly selected modifications.
