• [x] This is not a feature request (existing functionality does not work, not missing functionality). I will request features on forum or via support.
• [x] I've searched and did not find a similar issue.

Describe the bug The labels pricing.monthly_label and pricing.yearly_label stay in the language the app starts up with, although the app's language has been changed.

To Reproduce Steps to reproduce the behavior:

1. Start the app in language A, for example, English. In the Subscription popup, the two labels are in language A, i.e. "Yearly" and "Monthly";
2. Change the app's language to another one, call it B. All parts of the app that have been translated to B are now shown in B;
3. Open Subscription popup;
4. Although the two labels are already translated to B, they are still shown in A, i.e. "Yearly" and "Monthly".

Expected behavior The two labels if have been translated should be shown in the language the app is currently using.
