Unable to translate a string because other strings are saved too.

I want to translate 1 string.

When i search for it, other strings show up too. When i change the string i want, Drupal says that i can’t use HTML strings. But they are only on the other strings that show up too. Not in the one that i want to translate.

See screenshot for detailed example:


How can i just edit the string “Submit” without saving other strings.

Thank you!
