Some pre-written messages in Spanish not available in OJS 3.4.X

Describe the issue or problem
Some pre-written messages (in the editorial process stages) are only available in English. I have already mentioned this problem since the first update to OJS 3.4.0-0, but in the latest update (3.4.0-7) there are some issues.

Is there a way to fix this problem so that pre-written messages from the different production stages that do not yet exist in Spanish?

What application are you using?
OJS 3.4.0-7
