I need help with Localization (culture)

I created a Spanish localization languaje for my game:

Gathered, counted, compiled…everything looks good.

I test it in the editor by changing editor preferences and works.
I checked and adjusted all my widgets and I can swap language pressing the world icon on the top.
Everything looks ok.

I have the Localization\Game folder and inside I have both english and spanish:

both en and en-ES folders contain two files:

localization to package:

I want to change language at runtime for testing by using this:

when switching to english it seems to work ok. this is the log:

LogPackageLocalizationCache: Processed 36 localized package path(s) for 1 prioritized culture(s) in 0.013046 seconds
LogSlate: FontCache flush requested. Reason: Culture for localization was changed

[Internationalization]
Culture=en

still not working.

I just get Spanish if I set it in the editor preferences like this:
