translating mailpoet

Hi, I have read that your mailpoet is not compatible with wpml, but when using string translation, I CAN see the string I put for the widget text. I translated it, but it doesn’t show the translation on the page. I THINK that it has been working before v. 4.6. The title shows the correct translation, only the text (description) of the widget doesn’t show up. Any ideas? I scanned the plugin and it shows the translation as completed.
