Term recognition not working for "draft" segments

Dear colleagues,

I'm Working with Trados Studio 2017 and have a strange problem. When I add a new term to my TM, confirm (ctrl + enter) the translated segment and move to another not translated or draft segment, the term I just added ist not recognized in the new segment. Strangely, when I confirm the segment, the Term Recognition "wakes up again" and marks with the red superior line the term just added.

Does anyone have the same problem?

Best regards
Hans
