Sticky Label issue: "https://In evidence"

Hi, thanks for your work.
I had an issue modifing theme option.
In the “Sticky Posts” i edited the “Sticky Label”.
Now my “Featured” text display like “https://In%20evidence” or “https://featured”.
I’m using a child theme, with no code editing.
The issue appened when i changed the first time the default text, and than i can’t go back.
Thanks in advance fot your support.
