New DeepL plugin for Studio 2019: empty segments with ZH-SI and JP


We have downloaded the latest DeepL plugin version ( that supports JP and ZH-SI and tested it with several file types. 

Regardless of the file type, we´ve noticed that during the pre-translation step, some target segments do not get populated with the MT proposal and are left empty. Nonetheless, the MT output appears in the translation proposal box when you position the cursor on the affected segment.

We couldn´t identify any pattern, this happens mostly when the segments contained cf tags, but it also occurs with segments that contain no tag. Also, the issue is not related to any segment specifically: we tried to reprocess the same files twice by creating 2 different projects and the segments returning this issue are different in each project.

Also, the issue seems to affect only projects where ZH-SI and JP are either the source or the target language.

Any idea of what the issue could be?
