Why is FB duplicating search and library paths?

I thought this was the source of another issue (it wasn’t) but it also seems strange that it is duplicating path information as shown in the attached files. Why is this happening?

It’s impossible to answer without knowing what settings you have on the Delphi Action in FinalBuilder, and knowing what your library path and project search path contains.
