You’re currently using TradingView v1, which doesn’t support the default layout feature. The indicator label setting is saved within the layout. To avail the default layout feature, I’d suggest switching to TradingView v2, which can be found under ‘Chart Settings’ on your profile page. Once there, you can choose the indicator label and opt to ‘Save as Default Layout’. This will ensure your preferences are saved in the default settings. For a comprehensive understanding of all the features available in TradingView v2, I encourage you to refer to the link.
