Translation does not display

I have a side bar made with the Advanced Floating Content plugin and I already added a translation from English into German, but when the site changes to german the translation I added does not display.

I already marked the box Make ‘Advanced Floating Content’ translatable and also under WPML-> Settings I checked the box Translatable – only show translated items for the Advanced Floating Contento, but still the translation in German doesn’t display.

Any ideas about what is wrong? Thank you very much in advance.
