Online Vault new UI beta - Set Inactivity Timeout is not working

Online Vault new UI beta - Set Inactivity Timeout is not working

I go to Settings > Personalization. I changed the value from the default 15 Minutes to 1 Week, clicked on Save. Page shows a notification "Settings updated successfully".

I go to another page, then come back to Settings > Personalization. Set Inactivity Timeout is again showing 15 Minutes.

Please fix.
