How do I change a field’s display default?

Hello, I want to modify the default display text of the field displayed on the front-end page by the UsersWP plug-in.
I have referred to the program file location corresponding to the displayed text recorded in the userswp-en_US.po file in the languages ??directory.
But I still have the following text:

Password
Bio
Old Password
New Password
Confirm Password

Even if you modify the corresponding places in the program file according to the userswp-en_US.po file,
However, on the front-end page, the fields that display the above text still cannot be changed to display the text I set in the program file.

Thank you for your assistance.
