Missing string translation

[sododesign]

Hi guys, I noticed that in the Widget Image missing the translation for Insert Media string. In my case, Italian, the po file is translated to 100%, but the string is highlighted in red in English. You can kindly check and add the ability to be able to put these two translatable strings?

Thanks so much,
Davide
