I am unable to change Locale options in Stores >> Configuration >> General tab Configurations. After saving the configurations it shows ‘You saved the configuration.’ but there is no change.
Flushed the cache, reindexed but still no change.
Checked console but no error in console.

Can’t save any general configuration in Default Config store view.
