Results along line - plate analysis results

Good day,

I would like to query a few observations relating to the 'results along line' plate layout. As a preamble to these queries, the model in question has been built using plate elements to form the shear walls and beam elements to form the moment frame and boundary elements surrounding the shear wall system. Please see the list of queries below:

1. Using the results along line command, I have observed that any line drawn along the x-axis will cut through all the walls within the model, given they exists within that plane. This is true, even in the case where I have created an isolated view for a specific wall panel wall using the 'view selected objects only' option.  I have tried the instructions given in the STAAD online wiki and this still occurs (See link - https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/29627/using-results-along-line-to-cut-one-wall-excluding-others-around-it). How can I work around this?

2. The skewed wall panel along the right edge of my model has reported null/zero values for the cut line along plate P188 to P151, while all other wall panels have reported values. Given this wall is the longest in the model, I would expect it attract considerably lateral loads, making this observation even more peculiar. What could be the cause of this?

3. I observed that the naming conventions relating to the Total Force tab have been changed. Being that my primary use of this will be for designing the shear wall elements, is the following interpretation of the tab correct?
FS-Line - Shear Force
FT-Line - Axial Load
MR-Line - In-plane moment

I have attached the model for reference as well.
