Background of the issue:
I am using Montonio for Woocommerce and trying to maintain the correct language translation for bank and card payments on my site. My main language is Estonian, and I want the translation 'Maksa pangas' to appear in Estonian. The issue can be seen on this page: enlace oculto.
Symptoms:
With each automatic update, the translation 'Maksa pangas' in Estonian turns into Russian, even though my main language is Estonian.
Questions:
Why does the translation 'Maksa pangas' change to Russian after each automatic update?
How can I ensure that the translation remains in Estonian after updates?
