Get Visible Text gets no Clipping Region and Selector

Hi there,

I am using Scrap Relative under Image Recording, it does get the data during the setting. But when I finish and click “Save & Exit”, the activities of Attach Window, Find relative image, Translate clipping region, Get Visible Text ‘document’, and Reset clipping region are generated.
However when I run the program, it cannot return the data (just blank). On detail checking, I found that the Get Visible Test ‘document’ has null value in the properties of ClippingRegion and Selector. I wonder if it is a bug or just I missed something ! If I manually put back the values for these 2 properties, the program can get the data.

Any advice ?

Further info: I am using Native method. If using OCR method the program can get the data.
