We update our features and functionality roughly once per two weeks. Usually, these updates have some impact on the texts appearing on the widget and in automated end-user emails. We try to keep the "other language" texts updated too, but sometimes the translation updates don't keep up with the feature updates.
​
So should you find English expressions in "your" language version of widget and emails, just contact us, preferably with a screen print of the problem, and if in any way possible, your proposal for a translation into "your" language. 

We will make sure that with the next update those English expressions are replaced with expressions in "your" language.
