I don't really know what the issue is, but DeepL sometimes doesn't translate French texts. This is like the 4th text I try to translate from French to no matter what language, but it keeps the same as original. It only happens with French. Check evidence below:

As I said, this is not the 1st time it happens, and I need to use the "Alternatives" feature each time it happens to obtain an accurate translation. This seems like API issue somehow.
