"Progress" word in the achievement details screen isn't translated in Spanish (Spain)

UPDATE: This was fixed in 1.19.50.

I recently noticed an untranslated word in the achievement details in the Spanish language.

It says "Progress" (Same as English), while in Spanish it would be "Progreso".

Steps to Reproduce:

1. Set your language in Spanish (Spain) / Español (España).

2. Go to the achievements screen and click on any achievement to enter the achievement details screen.

3. See how "Progress" is untranslated.

Observed Results:
The achievement details screen says "Progress" while being in Spanish.

Expected Results:
The achievement details screen says "Progreso" because it's in Spanish.
