Origin offset to text layer changes uncontrolled

Support
1

I have a text layer that appears over different keyframes. However, in a certain keyframe the text has changed position vis-a-vis the origin (green dot). So the position of origin hasn’t changed, but the text is now shown higher up. In the next keyframe it’s back to normal.

How is that possible? I couldn’t even find a parameter, let alone a keyframable parameter, that controls this off-set.

There is a parameter called “Orientation” that also influences where the text is rendered.
Check if the second parameter suddenly get’s higher for that one key frame.
