Create Angular SectionViews from a Multi Segment Gridline?

Hi, I’m trying to create a continuous section view by the line path of multi-segment gridline in Revit,

the process looks fine and the result of the view ranges (length, depth and height) are all correct,

the only problem is the view section got offset from the referenced gridline,

please, really need some help to solve this problem,
or any advice to achieve a similar scope of angular section views will be appreciate,

Thanks in advance :]
