Sorry for the delay, but i was out of office.
The code snippet show an entry in the localization.js wich is loaded by the locale manger.
So weekAndDay is the Id of an preset and i hoped that preset manager or scheduler localize the name-property of this preset according to the id. Localization guids so nothing about localize a name of a preset, only date and time formats.
viewPreset has a
name property that may contain human readable text.
This property has not being localized, I've opened a ticket for that https://github.com/bryntum/support/issues/5195
As a workaround, you could manually go throw it in
scheduler.presets store and apply localized name.
but scheduler shows only the key weekAndDay...
Please let us know where in the Scheduler you see this key?
All the best,
